Trinuclear Complexes of Zinc(II) and Cobalt(II) with a Tridentate Schiff Base Ligand Containing Phenolate and Pyridine Donor Groups
Abstract. Acetate trinuclear metal complexes of ZnII and CoII with
the potentially tridentate Schiff base ligand, having mixed phenolate,
imine, and pyridine donor groups, HL, were synthesized. The complexes
were characterized by microanalysis, LSI mass spectrometry,
IR, UV/Vis spectroscopy, and magnetic measurements. Crystal structures
of [M3L2(OAc)4] (M = ZnII, CoII) complexes, were also determined.
The X-ray structures show the presence of trinuclear complexes with metal ions joined by phenolate and acetate bridging groups. The
ligands coordinate to the metal ions through the imine nitrogen and
their corresponding attached pyridyl and phenolate groups. The coordination
environment for the metal ions is completed by bridging acetate
anions to generate an octahedral coordination arrangement for the CoII
complex and mixed distorted, bipyramidal trigonal and octahedral arrangements
for the ZnII complex.
