摘要
Two novel complexes [Zn(Him-thz)2(NO3)]·NO3 1 and [Ni(Him-thz)2(NO3)]·NO3 2 (Him-thz = 2-(2'-thiazole)-4,4,5,5-teramethyl-dihydro-1H-imidazolyl-1-hydroxy) have been prepared and structurally characterized by X-ray diffraction method. Both complexes crystallize in orthorho- mbic, space group P21 21 2, Z = 2. Crystal data for 1: ZnC20H30N8O8S2, Mr = 640.2, a = 13.1630(14), b = 10.5149(11), c = 10.6670(11) A°, V= 1476.4(3)A°^3, Dc = 1.440 g/cm^3, μ(MoKa) = 1.028 mm^-1, F(000) = 664, R = 0.0398 and wR = 0.0901 for 2131 observed reflections with I 〉 2σ(I). Crystal data for 2: NiC20H30N8O8S2, Mr = 633.36, a = 13.1611(7), b = 10.4833(6), c = 10.6928(6) .4,, V = 1475.30(14)A°^3, Dc = 1.426 g/cm^3 ,μ(MoKa) = 0.854 mm^-1, F(000) = 660, R = 0.0281 and wR = 0.0797 for 3099 observed reflections with I 〉 2σ(I). X-ray analysis reveals that the crystal structures consist of [M(Him-thz)2(NO3)]^+ (M = Zn, Ni) moiety and a NO3^- anion. Both Zinc(Ⅱ) and Nickel(Ⅱ) ions are six-coordinated with distorted octahedral geometries.
