The title complex [Cu(NO3)2(H2O)2(3,3-azpy)2] (3,3?azpy = 3,3?azobispyridine) has been synthesized and characterized, and its crystal belongs to the triclinic system, space group P with the following crystallographic parameters: a = 7.4161(2), b = 8.1754(3), c = 10.7545(4) ? a = 92.958(2), b = 109.978(1), g = 93.369(2)? V = 609.96(4) ?, C20H20N10CuO8, Mr = 592.00, Dc = 1.612 g/cm3, m(MoKa) = 0.964 mm-1, F(000) = 303, Z = 1, the final R = 0.0494 and wR = 0.1269 for 1945 observed reflections (I > 2s(I)). X-ray analysis reveals that the Cu atom adopts a distorted octahedral (4 + 2) coordination. The four closer donor atoms include two N atoms of 3,3?azpy and two O atoms of the coordination aqua with the CuN and CuO distances of 2.014(3) and 1.974(3) ? respectively. Two longer out-of-plane CuO bonds (2.450(3) ? from nitrate complete the strongly distorted octahedral coordination of the Cu atom. Hydrogen bonds are formed through H atoms of each coordination aqua with the remaining N atoms of 3,3?azpy and O atoms of nitrate. A two-dimensional network is constructed by hydrogen bonds and p-p interactions.
