    Description / Table of Contents: Trinuclear Sandwich Compounds Containing Dialkylphosphonate as Bridging Ligands: Synthesis, NMR-, IR-, and Raman StudiesThe solvolysis of [C5H5Co{P(OR)2O}3BF]BF4 (3) leads to the half-sandwich complex [C5H5Co{P(O)(OR)2}2{P(OH)(OR)2}] (4). 4 is a novel O3-tripod ligand which reacts with the bivalent metalions M = Mg, Ca, Sr, Ba, Pb, Mn, Fe, Co, Ni, Cu, Zn, Cd, Hg to give the trinuclear compounds [{(C5H5)Co[P(O)(OR)2]2}2M] (5a-m). In these sandwich like complexes the dialkylphosphonate ligands are forming bridges of the type Co—(P—O)3—M—(O—P)3—Co between the three metal centers. The 1H NMR spectra are discussed. Due to a non-regular octahedral coordination of the central ion M = Cu and Hg the vP = O and δP = O bands in the IR spectra of 5j and 5m are split. It is shown by means of the IR spectra that the Jahn-Teller distorted octahedral coordination of CuII in 5j is changed to a regular one under the influence of high pressure (35 kbar).
    Notes: Es wird über die Synthese des Halbsandwichkomplexes [C5H5Co{P(O)(OR)2}2{P(OH)(OR)2}] (4) aus [C5H5Co{P(OR)2O}3BF]BF4 (3) berichtet. 4 ist ein neuartiger O3-Tripodligand, der mit den zweiwertigen Metall-Ionen M = Mg, Ca, Sr, Ba, Pb, Mn, Fe, Co, Ni, Cu, Zn, Cd, Hg zu dreikernigen Verbindungen der Zusammensetzung [{(C5H5)Co[P(O)(OR)2]3}2M] (5a-m) reagiert. In den sandwich-artigen Komplexen 5 bilden die Dialkylphosphonatliganden Brücken der Art Co—(P—O)3—M—(O—P)3—Co zwischen den drei Metallzentren. Die 1H-NMR-Spektren werden diskutiert. Im IR-Spektrum beobachtet man als Folge der nicht regulären Oktaederkoordination beim CuII-Komplex 5j und bei der Quecksilberverbindung 5m eine Aufspaltung der VP = O und δP = O-Banden. An Hand der IR-Spektren wird gezeigt, daß die Jahn-Teller-Verzerrung des CuII-Komplexes 5j unter einem Druck von 35 kbar aufgehoben werden kann.

    Description / Table of Contents: Multiple Center-Bridged Donor-Acceptor complexes of Dimethylmagnesium with F⊖, CI⊖, CN⊖, N3⊖, NCO⊖ und SCN⊖The tetramethylammonium salts [(CH3)4N]⊕X⊖ with X⊖ = F⊖, CN⊖, N3⊖, and NCO⊖ react in ethereal solution with dimethylmagnesium to form the donor-acceptor complexes [(CH3)4N]2{[(CH3)2Mg]2X}2. The vibrational spectra suggest that the complex anions possess the methyl-bridged structures 1 or 4. Equimolar amounts of (CH3)2Mg react with [(CH3)4N]⊕X⊖ (X⊖ = CI⊖, N3⊖, SCN⊖) to yield adducts of composition [CH3)4N]2[(CH3)2MgX]2. The anions appear to have centrosymmetric methyl-bridged structures of the type 5-7.

In den komplexen Anionen liegen nach den Schwingungsspektren (IR, Raman) Methylbrücken enthaltende Strukturen vom Typ 1 bzw. 4 vor. Durch Anwendung äquimolarer Mengen (CH3)2Mg/[(CH3)4N]⊕X⊖ entstehen mit X⊖ = CI⊖, N3⊖, SCN⊖ Addukte der Zusammensetzung [(CH3)4N]2[(CH3)2MgX]2, deren Anionen methylverbrückte zentrosymmetrische Strukturen vom Typ 5 - 7 aufweisen.

    Notes: Lithiated Phosphane Imines. Synthesis and Crystal Structures of [LiCH2PMe2NSiMe3]4 and [LiCMe2P(iPr)2NSiMe3]2The title compounds were prepared by the reaction of Me3-SiNPMe3 and Me3SiNP(iPr)3, respectively, with n-Butylli-thium at 20°C in n-hexane solution. They form white, moisture- and oxygen-sensitive crystals, which were characterized by IR spectroscopy and by crystal structure determinations. - [LiCH2PMe2NSiMe3]4 (1) forms a Li4 tetrahedron, the faces of which are capped with CH2 groups with average Li-C distances of 233 and 251 pm, while the nitrogen atoms occupy the corners of the Li4 tetrahedron. - [LiCMe2P(iPr)2N-SiMe3]2 (2) forms molecules of symmetry C2 in which the lithium atoms have coordination number three by two carbon atoms and one nitrogen atom with Li-C distances of 215.2 and 237.9 pm and Li-N of 192.8 pm.

    Notes: Organo-Zinc Phosphaneiminato Complexes with Heterocubane StructureThe organo-zinc heterocubanes [ZnR(NPMe3)]4 with R = CH3 (1) and n-C4H9 (2) were prepared by the reaction of [ZnBr(NPMe3)]4 with MeLi and nBuLi, respectively, in hexane solution. In a similar reaction of nBuLi with [ZnI(NPMe3]4 the phosphaneiminato complex [Zn4I(nBu)4(NPMe3)3] (3) is formed. 1-3 were characterized by IR, NMR and MS spectroscopy, and by crystal-structure determinations. 1 and 2 possess heterocubane structures in which the zinc atoms are linked via μ3-N bridges of the phosphaneiminato groups, and all bond angles in the Zn4N4 core are close to 90°. A distorted heterocubane structure is observed for 3 with one of the NPMe3 moieties replaced by an iodine atom.
