Novel vanadium(iii/iv) compounds with the diamidate ligand 1,2-bis(2-pyridinecarboxamide)benzene (H₂bpb)

Abstract

Reaction of the diamidate ligand H₂bpb with VCl₃ depending on the base affords either the compound NHEt₃{trans-[V^IIICl₂(bpb)] } 1 or [V^III(Hbpb)₃]·2CHCl₃ 2; aerial oxidation–hydrolysis of 1 gives the dimeric species [VOCl(Hbpb)]₂·2MeNO₂ 3; the X-ray crystal structures of 1, 2 and 3 are reported.
