Several titanium(m) complexes incorporating the chelating diamidoamine ligand [(Me3SiNCH2CH2)2NSiMe3]2-[NN2] are described. The reaction between Li2[NN2] and TiCl3(THF)3 (THF = tetrahydrofuran) resulted in the formation of the dimeric titanium(III) chloride {TiCl[NN2]}2 1, from which the monomeric titanium(III) alkyl Ti{CH(SiMe3)2}[NN2] 2 could be synthesized via a salt metathesis route. The alkyl complex 2 was found to react with hydrogen gas to form the thermally stable, dimeric, diamagnetic titanium(III) hydride {TiH[NN2]}2 3; density functional calculations on a simplified model system of 3 indicated the presence of a weak Ti-Ti s- interaction. The solid-state structures of 1, 2, and 3 are described.
