摘要：

The title compound 1 was unexpectedly synthesized by the reaction of ClTi(i-PrNCH2CH2)(3)N and excess NaNH2 in THF. A single-crystal X-ray diffraction study of 1 revealed that two azatitanatrane units and a sodium atom are bridged by a T-shaped nitrido ligand, the first such structure unsupported by a metal-metal bond. Structural evidence is presented for substantial pi bonding in the TiN(nitrido)Ti bridging linkages that at least partially accounts for the unexpectedly long sodium-nitrido distance.
