Abstract

The chelate complex, (C₅H₅)₂MoS₂C₆H₄, isolated from a reaction mixture of (C₅H₅)₂MoCl₂, benzene-1,2-dithiol, and triethylamine in aqueous benzene, exists in two conformations statistically distributed in the crystal and differing from each In both cases, the molecule possesses a mirror plane bisecting the two cyclopentadienyl rings as well as the chelate and benzene ring. The coordination polyhedron, defined by the cyclopentadienyl ring centroids and the sulfur atoms, around the molybdenum atom is a distorted tetrahedron of nearly C_2ν symmetry. The S₂C₆H₄ plane is folded out of the MoS₂ plane by an angle of 9°.

Zusammenfassung

Der aus einer wässrig-benzolischen Reaktionsmischung von (C₅H₅)₂MoCl₂, Benzol-1,2-dithiol und Triäthylamin isolierte Chelatkomplex (C₅H₅)₂MoS₂C₆H₄ kommt im Kristall in zwei statistisch verteilten Konformationen vor, die sich in der relativen Lage der Cyclopentadienylringezueinanderauf Lücke bzw. auf Deckungunterscheiden. In beiden Fällen besitzt das Molekül eine Spiegelebene, die beide Cyclopentadienylringe sowie den Chelat- und den Benzolring halbiert. Der durch die Schwerpunkte der Cyclopentadienylringe und der Schwefelatome beschriebene Koordinationspolyeder am Molybdänatom ist ein deformierter Tetraeder mit annähernd C_2ν-Symmetrie. Die S₂C₆H₄-Ebene ist um 9° aus der MoS₂-Ebene herausgefaltet.

Electronic communication within flexible bisdithiolene ligands bridging molybdenum centers
2019, Organometallics
Bimetallic molybdenum dithiolene complexes involving two flexible ditopic conjugated linkers have been synthesized and characterized by electrochemistry, spectroelectrochemistry, and single crystal X-ray diffraction. The electrochemical investigations evidence that the two metallic bisdithiolene moieties are electronically coupled in the monocationic state. DFT and TD-DFT calculations further suggest that the intervalence charge transfer within both monocations is essentially localized on the ligand and can be described as an intraligand charge transfer (ILCT).
CpCo(dithiolene) complexes of highly flexible oxddt ligand with two different Z-shaped and U-shaped structures
2009, Journal of Organometallic Chemistry
[CpCo(oxddt)] complex (2, oxddt = o-xylenediyldithioethylene-1,2-dithiolate, Cp = η⁵-cyclopentadienyl) was obtained from o-xylenediyldithioethylene-1,3-dithiol-2-one (OC(oxddt)) (1). 2 further reacted with diazoalkanes (N₂CHR) to form some alkylidene-bridged adducts [CpCo(CHR)(oxddt)] (R = H (3a), SiMe₃ (3b)). Adduct 3a further reacted with protic acids (HX) to give some S-methylated adducts [CpCo(X)(oxddt)(S-Me)] (X = Cl (4a), OCOCF₃ (4c)), followed by the Co–C bond cleavage in the three-membered cobaltathiirane ring. Two different Z-shaped and U-shaped molecular structures were observed by X-ray diffraction studies. In the former structure (Z), the dithiolene and o-xylylene planes are located at almost parallel position each other, and in the latter structure (U), both planes are not parallel but the o-xylylene moiety is located closer to the dithiolene plane than the Z-shaped one. The Z-shaped structure involves 1 and 2. The U-shaped structure involves 3a, 3b, 4a and 4c. Complex 1 showed a one-dimensional chain through intermolecular π–π interaction in the crystal. Complex 2 had a dimeric interaction between dithioethylenedithiolate moieties (S₂C₂S₂) in the oxddt. The SiMe₃ group in 3b was placed at an exo-position with respect to the cobaltadithiolene ring due to a steric hindrance from the U-shaped oxddt ligand. In 4a, the X and Me groups are located at the opposite side of the dithiolene plane (anti-form) but in 4c, both groups are presented at the same side of the dithiolene plane (syn-form). The NMR analysis of 4a in solution indicated existence of both anti- and syn-isomers (7:1).
Organometallic dithiolene complexes of benzenedithiolate analogues with π-coordinating and π-interacting Cp* ligand
2009, Journal of Organometallic Chemistry
Organometallic dithiolene complexes, which were formulated as [Cp*M(dcbdt)] and [Cp*M(dcdmp)] (M = Co, Rh, Ir; Cp* = η⁵-pentamethylcyclopentadienyl, dcbdt = 4,5-dicyanobenzene-1,2-dithiolate, dcdmp = 2,3-dicyano-5,6-dimercaptopyrazine) were prepared from a low valent Cp*Co^I or high valent Cp*M^III species (M^III = Co^III, Rh^III, Ir^III). The UV–Vis absorption spectral and electrochemical data of them were obtained. The lowest absorption (HOMO–LUMO) energies of them became redshift in order of the Co > Rh > Ir complexes. The reduction potentials suggested that the central metal modifies their LUMO levels. The molecular and crystal structures of [Cp*Co(dcbdt)] (3a), [Cp*Co(dcdmp)] (4a) and [Cp*Rh(dcdmp)] (4b) were determined by X-ray diffraction studies. The cobalt complexes 3a and 4a were monomeric, formally 16-electron complexes and have two-legged piano-stool geometries. The crystal structure of 3a indicated some plane-to-plane intermolecular interactions such as benzene⋯benzene interaction on the dcbdt ligand and two Cp*⋯benzene π–π stackings. 4a showed plane-to-plane interaction with a pseudo-4-fold-symmetry arrangement between the pyrazine moieties on the dcdmp ligand. The rhodium complex 4b was dimeric in the crystal to form a criss-cross arrangement and had a three-legged piano-stool geometry, but it was monomerized in solution. The dimer of 3b was observed in the oxidation process of the cyclic voltammogram.
Structural flexibility of titanocene diselenolene complexes: Combined structural and VT NMR investigations
2007, Journal of Organometallic Chemistry
A comparative investigation on five different Cp₂Ti(diselenolene) complexes, i.e. Cp₂Ti(Se₂C₂Z₂) (Z = –CO₂Me), Cp₂Ti[Se₂C₂Z(CF₃)], Cp₂Ti(bds) (bds = 1,2-benzene-diselenato), Cp₂Ti(dsit) (dsit = 1,3-dithiole-2-thione-4,5-diselenato) and Cp₂Ti(ddds) (ddds = 5,6-dihydro-1,4-dithiine-2,3-diselenato) is performed based on structural and variable-temperature NMR data. Preparation of Cp₂Ti[Se₂C₂Z(CF₃)] involves the reaction of Cp₂TiSe₅ with an excess of methyl-4,4,4-trifluorotetrolate while Cp₂Ti(bds) is obtained from the bds²⁻ diselenolate and Cp₂TiCl₂. Their X-ray crystal structures have been determined, showing that Cp₂Ti(bds) is not isostructural with the sulfur analog Cp₂Ti(bdt). Similarly the structures of Cp₂Ti(dsit) and Cp₂Ti(Se₂C₂Z₂) were also determined from single crystal X-ray diffraction. All complexes exhibit a strong folding of the metallacycle along the Se⋯Se hinge, ranking from 47.8° in Cp₂Ti(Se₂C₂Z₂) to 52.3° in Cp₂Ti(ddds). VT NMR investigations on Cp₂Ti[Se₂C₂Z(CF₃)] and Cp₂Ti(ddds), complementing earlier results on the other complexes, show that the largest activation energies and associated folding angles are observed with the most electron rich diselenolenes (ddds, bds), a behavior closely related to that observed earlier in dithiolene complexes.
Formations and electrochemical behavior of mononuclear and binuclear molybdenum dithiolene complexes with nitrosyl ligands: Evidence for the formation of a coordinatively unsaturated species [Cp<sup>*</sup>Mo(NO)(dithiolene)]
2006, Journal of Organometallic Chemistry
The one-pot reaction of [Cp^∗Mo(NO)(CO)₂] with elemental sulfur and dimethyl acetylenedicarboxylate (C₂Z₂ (Z = COOMe)) gave the [2+2] cycloadduct of the mononuclear molybdenum dithiolene complex [Cp^∗Mo(NO)(S₂C₂Z₂)(C₂Z₂)] (1), and some binuclear complexes:[Cp^∗Mo(NO)(S₂C₂Z₂)]₂ (2), [Cp^∗₂Mo₂(NO)₂S₂(S₂C₂Z₂)] (3) and [Cp^∗Mo(NO)S₂]₂ (4).The reaction of [Cp^∗Mo(NO)(Cl)(μ-Cl)]₂ with OC{S₂C₂(COOMe)₂} in the presence of sodium methoxide also produced complex 2 and the paramagnetic Cp^∗Mo bisdithiolene complex [Cp^∗Mo(S₂C₂Z₂)₂] (5, Z = COOMe).The structures of complexes 1–5 were determined by X-ray crystal structure analysis.The nitrosyl ligands of complexes 1–4 showed a linear coordination to the molybdenum center (the Mo–N–O bond angles = 169–174°), and their N–O bond lengths were 1.17–1.20 Å.In the binuclear complexes 2–4, two nitrosyl ligands were placed at cis-position.Complexes 1 and 2 were characterized by cyclic voltammetry and spectroelectrochemistry (visible and IR). The electrochemical reduction of the dimeric complex 2 formed the monomeric dithiolene complex[Cp^∗Mo(NO)(S₂C₂Z₂)]⁻ (X⁻) whose lifetime was several minutes. When the anion X⁻ was electrochemically oxidized, the coordinatively unsaturated species X was generated, but it was immediately dimerized to afford the original dimeric complex 2. The reduction of the complex 1 included the elimination of the bridged DMAD moiety (C₂Z₂) to give the anion X⁻.
Reactions of α,ω-dithiolate ligands with bis(cyclopentadienyl) molybdenum dichloride; Crystal structures of Mo(η-C <inf>5</inf>H <inf>5</inf>) <inf>2</inf>{S(CH <inf>2</inf>) <inf>n</inf>S)} (n = 2, 3) and a layered hydrate, Mo(η-C <inf>5</inf>H <inf>5</inf>) <inf>2</inf>(SCH <inf>2</inf>CH <inf>2</inf>O)·4.5H <inf>2</inf>O
2005, Journal of Organometallic Chemistry
Reaction of bis(cyclopentadienyl)molybdenum dichloride 1 in ethanol with 1,3-propanedithiol 2 either in the presence of base or as its thallium derivative produces [Mo(η-C₅H₅)₂(SCH₂CH₂ CH₂S)] (5) containing a 6-membered ring with a chair conformation, structurally characterized by X-ray diffraction. However, reactions of compound 1 with 2,2′-thiodiethanethiol (3) or 2,2′-oxydiethanethiol (4) under the same conditions do not form complexes with 8-membered chelate rings but lead to thioether or ether bond cleavage, respectively, to yield as major products [Mo(η-C₅H₅)₂(SCH₂CH₂X)] (6, X = S, or 7, X = O), containing ligands which form 5-membered rings; crystal structures of 6 and 7 are reported and both contain chelating ligands with envelope conformations. Compound 7 readily incorporates water and the unusual crystal structure of the hydrate Mo(η-C₅H₅)₂(SCH₂ CH₂O) · 4.5H₂O comprises stacks of double layers of hydrated organometallic molecules of overall composition [{Mo(η-C₅H₅)₂(SCH₂CH₂O)}₂ · H₂O]_n separated by layers of hydrogen-bonded water molecules, interconnected by H-bonds between H₂O molecules and O-atoms of the 2-thioethoxy ligand.
