Vanadium (V) complexes based on a bis(pyridine)-imine ligand (HL); synthesis and crystal structure of a dioxovanadium (V) complex involving a ligand cyclisation

摘要

Synthesis and characterisation of two novel dioxovanadium (V) complexes based on (2-hydroxybenzylidene)-di(2-pyridin-2-yl)methylamine (HL) and 3-(2-hydroxyphenyl)-1-pyridin-2-yl-imidazo-[1, 5-a]-pyridine (HL'), which is the result of a vanadium-mediated oxidative cyclisation of HL, are reported.
