 Title    Synthese und Kristallstruktur von Re(NBCl3)Cl2[P(CH3)2C6H5]3, ein Komplex mit einer Nitridobrücke zwischen Rhenium und Bor Synthesis and Crystal Structure of Re(N BCl3)Cl2[P(CH3)2C6H 5]3, a Complex with a N itrido Bridge between  
 Abstract    R eN C l2(P M e2Ph)3 reacts as a Lewis base and with BC13 forms a nitrido bridge betw een Re and B. The resulting com plex R e(N B C l3)Cl2(PM e2Ph)3 crystallizes orthorhom bic in the space group Pn2! a with Z = 4. In the com plex each Re atom has six nearest neighbours in an almost octahedral arrangement with the NBC13 group being trans to one o f the Cl ligands. The difference betw een the two Re —Cl bond lengths (239,4 and 243,9 pm) indicates a weak trans effect o f NBC13. The linear bridge R e = N — B has bonding distances o f R e —N = 172,8 and N -B = 153 pm. B onding o f BC13 by the nitrido ligand causes a small

 Title    Synthese und Kristallstruktur von Cl3 Ti[N(SiMe2 Cl)(SiMe2NH2)]  
 Abstract    Cl3Ti[N(SiMe2Cl)(SiM e2NH2)] is yielded by reaction of TiCl4 with two molecules ClMe2SiNHSiMe3. A single crystal structure determination (P 2 , //*, a = 747.12(2), b = 1294.1(3), c = 1496.7(3) pm, ß = 90.30(3)°, Z = 4) shows a planar four-membered ring Ti-N-Si-N as the central feature of the monomers formed by a weak coordinative bond of the NH2 group to the Ti atoms. The monomers are connected to eive dimers via two Cl bridses linked to the Ti atoms.
