Tetrakis(triphenylphosphoraneiminato)titanium, [Ti(NPPh 3 ) 4 ] The title compound has been prepared by the reaction of [TiCl 2 (NPPh 3 ) 2 ] with methyllithium and cyclopentadienyllithium, respectively, in hexane solution. [Ti(NPPh 3 ) 4 ] · 3 C 7 H 8 crystallizes from toluene solution to form colourless, only slightly moisture sensitive crystals which were characterized by a crystal structure determination. Space group I4 1 /a, Z = 8, lattice dimensions at −80°C: a = b = 2160.7(2), c = 3334.2(3) pm, merohedral (110) twin, R = 0.077. The compound forms monomeric molecules with tetrahedrally coordinate titanium atoms and bonding parameters of TiN = 187.3 pm, PN = 155.1 pm, TiNP 150.4° in average.
