| Two novel complexes [CuL(H2O)3]•H2O (1) and [NiL(H2O)4]•H2O (2) (HL = 5-nitroorotic acid) have been synthesized and characterized by elemental analysis, IR, electronic spectra, EPR spectra and single crystal X-ray diffraction. Complexes 1 and 2 crystallized in the monoclinic system space group P21/n with lattice parameters of 1: a = 11.275(6) Å, b = 5.977(3) Å, c = 16.281(8) Å, ß = 91.579(7)°, Z = 4, R1 = 0.0460, ωR2 = 0.1162, and those of 2: a =16.026(2) Å, b = 10.107(3) Å, c = 19.360(7) Å, ß = 90.934(6)°, Z = 4, R1 = 0.0690, ωR2 = 0.0931. In the two compounds, the metal ions are six-coordinated by water molecules and ligands. |
