Abstract

A new tetranuclear complex of zinc(II) with P,P-diphenylmethylenediphosphinate and 2,2bipyridine ligands was synthesized. [(pcp)(2,2-bipy)Zn ( µ 3-pcp)Zn (2,2-bipy)]2·6H2O was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and X-ray diffractometry. The structure consists of tetranuclear complexes connected through water hydrogen-bonding interactions in corrugated 2D layers. Two crystallographically independent zinc ions are in a distorted five-coordinate environment, being surrounded by three oxygen atoms of phosphinate groups (fromtwo pcp ligands) and by two bipy nitrogen donors. Of the twoindependent pcp anions the first one utilizes all of its oxygen donors to coordinate one metal as bidentate and two metal atoms as a monodentate ligand, whereas the second one is only bidentate for one metal atom.
