Direct Synthesis, Crystal Structures and Thermal Analyses of the Two-Dimensional Cu(ntp)_2(H_2O)_4 Crystal (ntp=2-nitroterephthalate)

用直接法合成了配合物Cu(ntp)2(H2O)4,并测定了其晶体结构。分子式为C16H16CuN2O16。晶体属单斜晶系,C2/c空间群,晶胞参数为a=2.2665(7)nm,b=0.7068(2)nm,c=1.5755(4)nm,β=126.42(1)°。对晶体进行了DSC和TG-DTG热分析,根据结果提出了可能的热分解过程。

The Cu（ntp）2（H2O）4 coordination compound has been synthesized by direct method and its crystal has been cultured and characterized by X-ray single crystal structural analysis. The crystal is formulated as C16H16CuN2O16 and crystallized in monoclinic system, space group C2/c, with a=2.266 5（7） nm, b =0.706 8（2） nm,thermal decomposition mechanism of Cu（ntp）2（H2O）4 is predicted that it loses its four coordinated water molecules followed by a large weight loss and formation of copper oxide on heating.
