The synthesis of the [Cu(H2L)](NO3)(2) complex (I) and of a mixed-valent complex [Cu(H2L)Cl](2)[CuCl2]Cl center dot 0.5H(2)O (II), where L is chiral bis(menthane) propylenediaminodioxime. According to the data of single-crystal X-ray diffraction analysis, compounds I and 11 have ionic structures. In complex cations, the Cu2+, ion coordinates four N atoms of tetradentate chelate ligand, namely, the H2L molecule. The coordination surrounding of the Cu atom in I is a distorted square CuN4, while in 11, it is a distorted square in 11 has linear structure. The mutual arrangement of oxime pyramid CuN4Cl. The complex anion [CuCl2](-) groups in H2L corresponds to amphi-configuration of a ligand and therefore, intramolecular hydrogen bond O center dot center dot center dot H-O are formed in H2L. The complex cations in compound II are joined in dimers through hydrogen bonds Cl center dot center dot center dot H-O. The values mu(eff) for I and II are equal to 1.82 and 2.82 mu(B), respectively.
