摘要
Four new copper(II) complexes of formula [Cu(BQDTP)Cl2].2H2O (I), [Cu(BQDTP)Br2].2H2O (II), [Cu(BQDTP)(OH2)2](ClO4)2 (III) and [Cu(BQDTP)(NO3) (OH2)](NO3) (IV), where BQDTP is 1,5-bis(quinoline-8'-yl)-1.5-dithiapentane, have been synthesized and characterized by elemental analysis, conductivity measurements, IR and ligand-field spectral studies and magnetic susceptibility measurements. The X-ray crystal structure of IV has been solved at 293 K by single-crystal X-ray analysis. It consists of [Cu(BQDTP)(NO3)(OH2)]+ cations and nitrate ions, which are connected by hydrogen bonds to a water molecule. The coordination geometry about the copper atom is an elongated octahedron. The measured bond distances are: Cu-S = 2.343(3) and 2.507(3) angstrom, Cu-N = 1.986(7) and 1.993(7) angstrom, Cu-O(water) = 2.030(6) angstrom and Cu-O(nitrate) = 2.677(7) angstrom. The IR and electronic spectroscopic data, conductivity and magnetic susceptibility are in agreement with the observed structure.
