    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.

The Crystal Structures of PPh4[X(I-C≡C-I)2] with X = Cl, Br, IThe complexes PPh4[X(I-C≡C-I)2] with X = Cl (1), Br (2), and I (3) have been prepared from the phosphonium salts PPh4X and 1-C≡C-I in dichloromethane solutions. 1-3 form colourless crystals, which according to crystal structure analysis crystallize isotypically in the space group P421m with two formula units per unit cell. The diiodacetylenes are coordinated by the halide ions X- in a distorted tetragonal fashion, the I-C≡C-I molecules being in μ2-bridging function. Thus, a polymeric anionic network [X(I-C≡C-I)2]nn- with a layered structure results.

    Description / Table of Contents: Crystal Structures of [TiF3(NPPh3)(HNPPh3)]2 and of HNPPh3The phosphoraneiminato-phosphaneimine complex [TiF3(NPPh3)(HNPPh3)]2 was obtained by the reaction of TiF4 with Me3SiNPPh3 in boiling dichloromethane. It crystallizes from 1,2-dichloroethane as yellow crystals which include four molecules C2H4Cl2 per dimeric formula unit. Space group P21/n, Z = 2, structure solution with 7270 independent reflections, R = 0.060 for reflections with I 〉 2σ(I). Lattice dimensions at -50°C: a = 1417.5, b = 1896.9, c = 1586.6 pm, β = 101.22°. The compound forms centrosymmetric dimeric molecules via μ2-F bridges with TiF distances of 194.6 and 223.3 pm, the longer one being in trans-position to the N atom of the (NPPh3)- ligand. Its TiN bond length of 177.7 pm corresponds with a double bond. The TiN bond length of the HNPPh3 donor molecule of 213.4 pm is typical for a donor acceptor bond.According to the crystal structure determination the phosphaneimine HNPPh3 forms monomeric molecules without intermolecular hydrogen bridges with a PN bond length of 152.4 pm. Space group P21/c, Z = 4, structure solution with 3229 independent reflections, R = 0.062 for reflections with I 〉 2σ(I). Lattice dimensions at -70°C: a = 1460.4, b = 928.9, c = 1096.6 pm, β = 93.35°.
