摘要：

Paramagnetic copper(H) complexes with N-(3-hydroximino-2-methylbutan-2-yl)methylamine (HL), namely, Cu(HL)Cl-2 (I), Cu(HL)(SO4) . 2H(2)O (II), and Cu(HL)(NO3)(2) (III), were obtained. The crystal structures of I and II were determined. The blue crystals of these compounds are monoclinic. For I (C6H14Cl2CuN2O): a = 8.820(1) Angstrom, b = 6.511(1) Angstrom, c = 18.255(2) Angstrom, beta = 92.86(1)degrees V = 1047.0(2) Angstrom(3), space group P2(1)/c, rho(calcd) = 1.679 g/cm(3), Z = 4 for R-1 = 0.0250; for II (C6H18CuN2O7S): a = 9.999(2) Angstrom, b = 9.927(2) Angstrom, c = 12.963(3) Angstrom, beta = 106.37(3)degrees, V = 1234.5(4) Angstrom(3), space group P2(1)/c, rho(calcd) = 1.753 g/cm(3), Z = 4 for R-1 = 0.0324. Crystals of I have a molecular structure. The Cu coordination polyhedron is a square bipyramid (2N + 2Cl + Cl + Cl) due to additional contacts with two Cl atoms from the neighboring molecules. Structure II is built from polymeric chains. The environment of the Cu atom is a distorted cis-octahedron (2N + 2O(H2O) + 2O(SO4)). Complexes I-III are characterized by IR and EPR spectroscopy.
