Synthesis and characterization of a thermally robust titanium dinitrogen complex. The crystal structure of [{[(Me₃Si)₂N]TiCl(pyridine)₂}₂(µ-η:η′-N₂)]

Reaction of trans-[TiCl2(tmeda)](tmeda =N,N,N′,N′-tetramethylethylenediamine) with one equivalent of LiN(Me3Si)2, followed by treatment with pyridine, led to the formation of a novel Ti-dinitrogen complex [{TiCl[N(SiMe3)2](pyridine)2}2(µ-η : η′-N2)].
