Bent versus linear imido ligands in five-co-ordinate molybdenum complexes

Abstract

A comparison of the molecular structures of the five-co-ordinate bis(imido) and imido alkylidene molybdenum complexes [Mo(NC₆H₃Prⁱ ₂-2,6)(L)(L′)], where L is a tridentate pyridinediolato ligand and L′ is either NC₆H₃Prⁱ ₂-2,6 or CHCMe₂Ph, strongly supports the notion that the nitrogen of the bent imido ligand in the bis(imido) complex is sp²-hybridised.
