| Abstract: | ![]()
In a template synthesis from copper(II) acetate, 2,6-diacetylpyridine, and semioxamazide (NH2CO CONHNH2), two copper(II) complexes, [Cu(dapsox)(H2O)]·H2O and [Cu(Hdapsox)](H2O)]ClO4, (where H2dapsox = 2′,2?-(2,6-pyridindiyldiethylidene)dioxamohydrazide) were obtained and characterized. The structure of the former complex was determined by a single-crystal X-ray analysis. CuII is located in a square pyramidal environment. The polydentate ligand, dapsox2− is coordinated in dianionic form, as an unsymmetrical quadridentate planar system forming one-membered and two-five-membered metal-chelate rings. The fifth coordination site is occupied by a water molecule. |
