Abstract:	Copper(II) complexes with (1R,4S)-1-N-morpholino-n-menth-8-en-4-one (HL), namely, Cu₂(HL)₂Cl₄] (I) and Cu₂(HL)LCl₃] · CH₃CN (II), were synthesized and characterized by X-ray diffraction analysis, magnetic susceptibility, and EPR methods. The complexes have binuclear structures. In compound I, the coordination polyhedron of CuCl₃N₂ is a square pyramid in planar Cu₂Cl₂ metal cycle; the exchange couplings of unpaired electrons of Cu(II) ions are weak. Complex II incorporates polyhedra of CuCl₂N₂ (flattened tetrahedron) and of CuCl₂N₂O (trigonal bipyramid). The Cu₂ClNO metal cycle is nonplanar with antiferromagnetic exchange coupling and exchange parameter –2J = 182 cm^–1. The EPR spectrum of compound I are analyzed.
