Abstract
The binding of 3d transition metals to maleic hydrazide (3,6-dihydroxypyridazine) has been investigated. Cobalt(II), copper(II), manganese(II) and nickel(II) complexes of maleic hydrazide have been prepared, crystallized and studied by various spectroscopic techniques. X-ray crystallographic structures of ML2·nH2O complexes with all four metal ions have been obtained. In all of the complexes two maleic hydrazides bind as unidentate ligands. Water molecules occupy the remaining coordination sites. In the cobalt(II) and nickel(II) complexes, which are isomorphous, the ligand binds through a single ligand nitrogen atom whereas in the manganese(II) and copper(II) complexes the ligand binds through a ligand oxygen atom. The metal ions all have six coordinate octahedral geometries except the copper(II) complex which has a five-coordinate square pyramidal geometry.
