The MoVI atom in the title complex, [MoCl(C9H10BN6)(C12H10N2)2] or TpMo(NNPh2)2Cl, where Tp = HB(C3H3N2)3− and Ph = C6H5, has a distorted octahedral environment afforded by the facially coordinated Tp ligand, two terminal NNPh2 ligands and the chloro ligand. The bond distances Mo—N of 1.773 (3) and 1.780 (3) Å, N-N of 1.319 (4) and 1.312 (4) Å, and bond angles Mo—N-N of 167.1 (2) and 170.9 (3)°, in the Mo(NNPh2)2 moiety, together with the absence of pyramidalization on the N atoms remote from the Mo atom, are indicative of an extensive delocalization of the π-electron density throughout the Mo—N—N system.
