 Title    Die isoelektronischen Molekülkomplexe TiCl3(NPPh3) und TiCl3(OSiPh3)  
 Abstract    The Isoelectronic M olecular C om plexes TiC l3(N P P h 3) and T iC l3(O SiPh3) Thilo R übenstahl, D o ro th ea W olff von G udenberg, F ra n k W eller, K u rt D ehnicke* TiCl3(NPPh3) and TiCl3(OSiPh3) have been prepared from titanium tetrachloride and Me3SiNPPh3 and HOSiPh3, respectively. Both complexes were characterized by IR spectrosco­ py and by crystal structure determmations. TiCl3(N PPhj): Space group R3, Z = 6, structure analysis with 959 observed unique reflec­ tions, R = 0.039. Lattice dimensions at -6 8 °C: a = b = 1370.5(7), c = 1845.9(9) pm. TiCl}(OSiPh3): Space group P2,/c, Z = 8, structure analysis with 4549 observed unique re­ flections, R = 0.049. Lattice dimensions at 19 °C: a = 2127.7(2), b = 947.2(1), c = 2136.8(1) pm, ß = 105.081(5)°. Both complexes form monomeric molecules in which the titanium atom is tetrahedrally coordinated by three chlorine atoms, the nitrogen atom of the phosphorone iminato ligand and the oxygen atom of the silyloxy group, respectively. The bond lengths TiN of 171.9(4) pm and TiO of 171.0(3) (in average) correspond to double bonds.
