The crystal belongs to the triclinic system, space group P1 with a = 11.7175（13）, b = 11.8873（13）, c = 14.0958（16） A, α = 74.889（2）, β= 78.228（2）, γ = 78.831（2）°, V= 1835.0（4） A3, Z= 1, Dc= 1.502 Mg/m3, Mr = 1660.17,μ = 0.662 mm-1, F（000） = 846, 2（MoKa） = 0.71073 A, the final R = 0.0585 and wR = 0.0577 for all observed reflections. The results show that the Cd（II） ion with a square antiprismatic geometry is coordinated by a N206 donor set, two NO2 sets from two ligands and two O atoms from a bidendate nitrate group. In the crystal, the O-H...O and N-H...O hydrogen bonds are helpful to consolidate the three- dimensional network.展开更多
