Abstract

The preparation and spectral properties of copper(II) complexes of two hydantoins are reported. Complexes of the general formula Cu(hyd)2(py)2, where hyd = phenytoin or nirvanol; and py = pyridine were prepared and characterized by infrared and ESR. Spectral data show that the copper atom is bound to the nitrogen atom of the hydantoin anion and to the nitrogen atom of the pyridine molecule to form 2:2:1 hydantoin:pyridine:copper complexes. The ESR data indicate that both complexes have tetragonal symmetry (g11 greater than g perpendicular greater than g e) with the unpaired electron in the d x2-y2 orbital.
