Treatment of TiCl4 with 2–4 fold excess of ButN(H)SiMe3 in CH2Cl2 resulted in the formation of orange crystals of [TiCl2(NBut)(NH2But)]4, the X-ray crystal structure of which has been determined. In the presence of excess pyridine, the reaction of TiCl4 with 1 equivalent of ButN(H)SiMe3 resulted in the isolation of the monomeric complex [TiCl2(NBut)(py)3]. Low pressure chemical vapour deposition of [TiCl2(NBut)(py)3] forms thin films of titanium nitride (a = 4.23(1) Å, XPS TiN0.75) at 600 °C.
