| 摘 要： | A copper（Ⅱ） complex Cu（L）2（NO3）2 constructed by the L （L = N-（4,6-dimethoxylpyrimidin）-N＇-（ethoxycarbonyl）thiourea） ligand crystallizes in monoclinic, space group C2/c with a = 16.2416（16）, b = 9.1385（7）, c = 22.0008（18） A, β = 108.077（2）°, V = 3104.3（5） A^3, Dc = 1.627 g/cm^3, Z = 4, C20H28CuN10O14S2, Mr = 760.18,μ（MoKa） = 0.920 mm^-1, F（000） = 1564, R = 0.0471 and wR = 0.1284 for 2239 observed reflections （I 〉 2σ（I））. X-ray diffraction shows the existence of weak complementary intramolecular N-H...O （DA） hydrogen bonds which further strengthen the coordination from the two L ligands with the Cu（Ⅱ） ion, intermolecular C-H...O hydrogen bonds and weak π...π stacking interactions, leading to the formation of a multi-dimensional supramolecular network.
