A group of zinc(II) complexes derived from potentially hexadentate (N4O2) acyclic ligands derived from Schiff bases and bearing pyridinyl and phenolic arms have been prepared and characterized. The crystal structures of two of them show that hydrolysis of the corresponding pro-ligand has occurred to give mononuclear zinc complexes. The co-ordination geometries around the zinc are approximately trigonal biopyramidal.
