EPR Study of [Cu(him)4]•2Br Complex

Abstract

The single crystal of [Cu(Him)(4)]center dot 2Br (Him: C3H4N2, imidazole) complex has been investigated at ambient temperature in three mutually perpendicular planes by EPR technique. The magnetic environments of [Cu(Him)(4)]center dot 2Br complex have been identified by EPR technique. The study reveals the existence of two magnetically inequivalent Cu2+ sites. The principal values of g tensors were obtained. The EPR parameters show that the paramagnetic centers have rhombic symmetry.
