The phosphinophosphido niobocene complex Cp2Nb(PHPh2)(PPh2) (2) was prepared by deprotonation of the cationic diphosphino complex [Cp2Nb(PHPh2)2]Cl (3). Complex 2 is thermally unstable and readily dissociates phosphine to give the ortho-metallated complex Cp2Nb(PHPhC6H4-). Crystal structure determination of 2 supported its formulation as the phosphinophosphido compound. The Nb-P(1) (phosphino) bond length is 2.524(2) A and Nb-P(2) (phosphido) bond length is 2.610(2) A.
