AbstractNb[NPPh3]Cl4 can be prepared by reacting NbCl4N3 with PPh3 in 1,2 dichloro ethane. The crystalline, yellow compound crystallizes in the monoclinic space group C2/c. The crystal structure consists of eight molecules, which are linked together via bridging chlorine atoms to centrosymmetric dimers. Thereby the niobium atoms obtain a sixfold coordination by one N and five Cl atoms. The triphenyl phosphine imine ligand is bound to niobium by its N atom. The approximate linearity of the resulting Nb-N-P group (angle Nb-N-P = 171°) and the distances Nb-N - 178 pm and N-P =164 pm can be interpreted by an sp hybridized N atom and double bonds to both the Nb and P atom.
