    Notes: The P-H-functional triferriophosphonium salts [{CpFe-(CO)2}3PH]2FeCl4 (1) and [{μ-CO(CpFeCO)2}{CpFe-(CO)2}PH]2FeCl4 (4) are easily deprotonated by DBU to the corresponding unstable triferriophosphanes 2, 5, which subsequently are oxidized by sulfur to the triferriophosphane sulfides {CpFe(CO)2}3P=S (3) and {μ-CO(CpFeCO)2}{CpFe-(CO)2}P=S (6), respectively. The photolysis of 3 results only in its decomposition by elimination of [CpFe(CO)2]2, whereas the photolysis of 6 cleaves off one CO ligand to give the new spiro compound (CpFeCO)(μ-η2-PS){μ-CO(CpFeCO)2} (7), where the P=S unit is η2-bonded to the 15-electron CpFeCO fragment, and the phosphorus atom bridges two 17-electron fragments. Compound 7 shows a new coordination mode of the PS unit where sulfur is also bound to one of the metal atoms. Compounds 6 and 7 can be regarded as first examples of a new class of PS complexes of transition metals. All compounds were characterized by IR, 31P{1H}- and 13C{1H}-NMR spectroscopy as well as mass spectrometry; for 6 the X-ray analytical data are given.

    Notes: Mono- and Diferriophosphanes and -thioxophosphoranesHerrn Professor Dr. Ekkehard Lindner zum 60. Geburtstag gewidmet.The substitution of organic substituents in phosphanes or thioxophosphoranes by the 17-electron fragments CpFe-(CO)2 (—Fp) leads to isolobal ferriophosphanes or -thioxophosphoranes. The mono- and diferriophosphanes FpnPPh3-n [n = 1 (3), 2 (4)] are obtained by deprotonation of the mono- and diferriophosphonium salts [FpnPPh3-nH]X [n = 1 (1), 2 (2)] with DBU. They are oxidized by sulfur giving the mono- and diferriothioxophosphoranes FpnPPh3-n(S) [n = 1 (5), 2 (6)]. Sulfide 5 arises also from the reaction of CpFe(CO)2Cl and Ph2PH(S)/DBU. The one-sided decarbonylation reaction of 6 leads to FpFp′PPh(S) (7, Fp′ = CpFeCO). The Fp substituents (17 electrons) in 3-7 coordinate as one-electron donors to the PhnP- or PhnP(S) units (n = 1, 2). The bridging functions in 4 and 6 are hitherto unknown. The molecular structures of the complexes 5-7 were determined by X-ray structure analyses.

    Notes: Complex-Chemical Synthesis of Cyclic 1.2-Dithiolato Ligands with the nido Cluster [(CO)3,FeS]2.  -  Molecular Structure and Partial S-Oxidation of Hexacarbonyl(μ2,-cis-1,2-cyclohexanedithiolato-S,S)diironThe cyclic alkenes, dienes, and trienes C6H10, C8C14, C5H6, C8C12 and C7H8 are inserted into the S-S bond of the nido cluster [(CO)3FeS]2 (1) by photochemically induced [2+2] cycloaddition reactions to give the complexes 2-6; thus, saturated and unsaturated cyclic 1,2-dithiolato ligands can be selectively built onto the complex in a μ2-bridging fashion. According to an X-ray structure analysis, the μ2-1,2-cyclohexanedithiolato-S,S complex 2a with the pseudotetrahedral skeleton [(CO)3FeS]2 crystallizes in the monoclinic space group P21/c; the S2 moiety is bridged by cyclohexane with 1,2-cis configuration. As an example, the partial S oxidation of 2a was carried out, leading to 2b by selective transformation of one thiolato into a sulfenato function.

    Description / Table of Contents: Directed Synthesis of Sulfinato-O and -S Complexes of Some Transition Metals, XIV Sulfinato-O,S Complexes of Palladium(II) and Rhodium(III)The directed preparation of the sulfinato-O,S complexes {R(O)OS}nM (2a, b; 5a, b) was successful for the first time by elimination of coordinated water from the sulfinato-S complexes {RS(O)2}nM(OH2)n [n = 2, M = Pd (1a, b); n = 3, M = Rh (4a, b)] by 2,2-dimethoxypropane. The O,S-linkage is unequivocally shown from their chemical behaviour and the i. r. spectra. The criteria necessary for the formation of sulfinato-O,S complexes are discussed.
    Notes: Durch Abspaltung von koordiniertem Wasser aus den Sulfinato-S-Komplexen {RS(O)2}nM(OH2)n [n = 2, M = Pd (1a, b); n = 3, M = Rh (4a, b)] mit 2,2-Dimethoxypropan gelang erstmals die gezielte Darstellung der Sulfinato-O,S-Komplexe {R(O)OS}nM (2a, b; 5a, b). Die O,S-Verknüpfung ergibt sich eindeutig aus dem chemischen Verhalten und den IR-Spektren. Die für die Bildung von Sulfinato-O,S-Komplexen notwendigen Kriterien werden diskutiert.

    Description / Table of Contents: Directed Synthesis of Sulfinato-O- and -S-Complexes of some Transition Metals, III. Investigations on the Metal-ligand Bond in Tris- and Tetrakis(sulfinato) Complexes of Transition MetalsThe tris- and tetrakis(sulfinato) complexes 1a-c to 3a-c and 6 of group V, VI, VIII and IV transition metals are obtained by the reaction of sodium salts of the aliphatic and aromatic sulfinic acids with soluble chlorides of the corresponding transition metals in water or ethanol at temperatures between 20 and 100°C according to equations (1) and (3). Depending on the solvent, (π-C5H5)2ZrCl2 (4) reacts with [CH3SO2]Na to form either 5 or 6. The structures of the newly prepared compounds, all sulfinato-O,O′ complexes, are discussed on the basis of i.r. and magnetochemical investigations.

    Description / Table of Contents: Directed Synthesis of Sulfinato-O and -S Complexes of some Transition Metals, VII. Sulfinato Complexes of Chromium(II), Manganese(II), Iron(II), Cobalt(II) and Nickel(II) with Mono- and Bidentate Nitrogen Ligands.The hitherto unknown, pseudooctahedral configurated bis(organosulfinato-O,O')dipyridine compounds of manganese(II), iron(II), cobalt(II) and nickel(II) 5a, b and 6a-8a are obtained by the reaction of the complexes (p-R-C6h4SO2)2M(OH2)2 1a, b and 2a-4a with pyridine according to equation (1). Linkage or stereo isomers cannot be detected.  -  White (p-CH3C6H4SO2)2Cr(OH2)2 (9) reacts with 2 moles of 2,2′-bipyridyl in water according to equation (2) to form the sulfinato-O complex 10, the corresponding manganese compound 1a adds only 1 mole of 2,2′-bipyridyl according to equation (3), yielding the sulfinato complex 11O,O'. In the case of 9 other solvents are not leading to linkage isomers. In contrast to this the sulfinato complex 11S, being linkage and structural isomeric to 11O,O' is obtained from 1a and 2,2′-bipyridyl in pyridine according to equation (4). The iron compound 2c reacts only in THF with 2 moles of 2,2-bipyridyl according to equation (5) to give the sulfinato complex 12O, which is in pyridine irreversibly converted into the S-isomer 12S according to equation (6). 12S can also be isolated from 2c and 2 moles of 2,2′-bipyridyl in pyridine according to equation (7). The newly prepared compounds are characterized on the basis of their i.r. and their electronic spectra as well as by magnetochemical investigations.
    Notes: Bei der Umsetzung der Komplexe (p-R C6H4SO2)2M(OH2)2 1a,b und 2a-4a mit Pyridin erhält man gemäß Gl. (1) die bisher unbekannten, pseudooktaedrisch konfigurierten Bis(organosulfinato-O,O')-dipyridin-Verbindungen von Mangan(II), Eisen(II), Kobalt(II) und Nickel(II) 5a, b und 6a-8a. Bindungs- oder Stereoisomere lassen sich nicht nachweisen.  -  Während (p-CH3C6H4SO2)2Cr(OH2)2 (9) in Wasser gemäß Gl. (2) 2 mol 2,2′-Bipyridyl unter Bildung des Sulfinato-O-Komplexes 10 aufnimmt, addiert die entsprechende Mangen-Verbindung 1a gemäß Gl. (3) nur 1 mol 2,2′-Bipyridyl, wobei der Sulfinato-Komplex 11O,O' entsteht. Andere Lösungsmittel führen bei 9 zu keinen Bindungsisomeren. Dagegen erhält man aus 1a und 2,2′-Bipyridyl in Pyridin entsprechend Gl. (4) den zu 11O,O' bindungs- und strukturisomeren Sulfinato-Komplex 11S. Die Eisen-Verbindung 2c setzt sich nur in THF mit 2 mol 2,2′-Bipyridyl gemäß Gl. (5) zum Sulfinato-O-Komplex 12O um, welcher in Pyridin irreversibel entsprechend Gl. (6) in das S-Isomere 12S übergeht 12S läßt sich gemäß Gl. (7) auch aus 2c und 2 mol 2,2′-Bipyridyl in Pyridin isolieren., Die neu dargestellten Verbindungen werden anhand ihrer IR- und Elektronenspektren, sowie durch magnetochemische Untersuchungen charakterisiert.

    Description / Table of Contents: Directed Synthesis of Sulfinato-O and -S Complexes of Some Transition Metals, XV. The Coordination Chemical Behaviour of the RSO2- Ligand in Silver(I) ComplexesThe preparation and characterization of the silver sulfinates RSO2Ag (1) (R = CH3 (a), C6H5 (b), p-CH3C6H4 (c)) are described extensively for the first time and their behaviour towards the N-heterocycles pyridine, 2,2′-bipyridine and 1,10-phenanthroline is investigated. Starting from 1 one obtains with these ligands without exception the temperature and light sensitive sulfinato-O complexes 2-4. Only in the case of (C6H5S(O)2)Ag(bipy) the unstable sulfinato-S complex 5 which is irreversibly transformed to its linkage isomer 3b can be isolated. The i. r. spectra are discussed in detail. The investigations show the HSAB model to be only of limited application to d10 ions.
    Notes: Die Darstellung und Charakterisierung der Silbersulfinate RSO2Ag (1) (R = CH3 (a), C6H5 (b), p-CH3C6H4 (c) werden erstmals ausführlich beschrieben und ihr Verhalten gegenüber den N-Heterocyclen Pyridin, 2,2′-Bipyridyl und 1,10-Phenanthrolin untersucht. Ausgehend von 1 erhält man mit diesen Liganden die durchweg temperatur- und lichtempfindlichen Sulfinato-O-Komplexe 2-4. Nur im Falle von (C6H5S(O)2)Ag(bipy) läßt sich der labile Sulfinato-S-Komplex 5 isolieren, welcher irreversibel in sein Bindungsisomeres 3b übergeführt werden kann. Die IR-Spektren werden diskutiert. Die Untersuchungen zeigen, daß das HSAB-Modell bei d10-Ionen nur beschränkt anwendbar ist.
