Titanium(IV) complexes with amidinate and/or hydrazido ligands

The complex [Ti2Cl4(NNMe2)2(py)3] (1) has been prepared via the reaction of TiCl4 with LiN(H)NMe2, followed by treatment with pyridine. Preparation of the complex [TiCl(PhC{N(SiMe3)2}2)2(MeNNMe2)] (2) was carried out by treatment of TiCl4 with Li[PhC{N(SiMe3)2}]tmeda, followed by reaction with LiN(Me)NMe2. The structures of 1 and 2 were determined by single crystal X-ray diffraction. The single crystal X-ray structure of Li[PhC{N(SiMe3)2}]tmeda (3) has also been determined.
