Zirconium(IV) Heterochelates

Abstract

Abstract New zirconium(IV) heterochelates of the type Zr(O)2 (BB) (AAA) (where AAA = Schiff base derived from benzoylhydrazide and salicylaldehyde, BB = orthophenanthroline, 2, 2′ -dipyridyl, ethylenediamine, tri-methylenediamine, tetramethylenediamine or orthophenylenediamine) have been synthesized and characterized on the basis of elemental analysis, molar conductance, molecular weight, IR and magnetic susceptibility measurements. AAA and BB behave as tridentate and bidentate ligands, respectively. The hetero-chelates are monomers, non-electrolytes, diamagnetic and seven-coordinate.
