Abstract:
Acetate and perchlorate dinuclear metal complexes of Co(II), Cu(II) and Zn(II) with the cresolate polypodal ligand having mixed phenolate and pyridyl pendant functionalities, H3L, have been synthesized. The complexes were characterized by microanalysis, LSI mass spectrometry, IR, UV–Vis spectroscopy, magnetic studies and conductivity measurements. Crystal structures of H3L, [Cu2(HL)(OAc)(H2O)2](OAc)·1.5H2O and [Zn2L(CH3OH)3](ClO4)CH3OH·2H2O complexes, have been also determined.
Keywords:Metal complexes   Polypodal ligand   Cresolate-bridge   X-ray structure
