SYNTHESIS AND STRUCTURE OF RIDIN-DIYLDIETHYLIDENE)-DIOXAMOHYDRAZIDOCOBALT(II) PERCHLORATE

The complex [Co(H(2)L)(H2O) (MeOH)](ClO4)(2)[H(2)L] = 2',2triple prime -(2,6-pyridindiyl-diethylidene) -dioxamohydrazide] has been prepared b y direct and template syntheses and characterized by elemental analysi s, IR spectroscopy, and magnetic susceptibility measurements. The crys tal structure of the complex has also been determined. The cobalt atom is seven coordinated with approximately pentagonal-bipyramidal geomet ry. The H2O and methanol are axial with the planar pentadentate H(2)L ligand forming the equatorial plane. The possible reaction mechanism h as been proposed.
