The crystal structure was determined by X-ray diffraction method and the chemical formula weight of the complex is 498.00. The crystal structure of the title complex belongs to orthorhombic system with space group Pbcn and cell parameters: a=3.107 2(4) nm, b=1.289 09(18) nm, c= 1.034 78(14) nm; and V=4.144 7(10) nm3, Z=8, Dc=1.596 g·cm-3, μ=1.197 mm-1, F(000)=2 048. The compound is an one-dimensional chain complex of infinite length which are connected with hydrogen bonds. The Cu(Ⅱ) was coordinated by two oxygen atoms and three nitrogen while the o atoms of Ac- groups did not participate in the coordination. The Cu(Ⅱ) formed a distorted tetragonal pyramid and the capacities of coordination to Cu(Ⅱ) of atoms was discussed. Besides, the TG-IR of the complex was analyzed. The kinetics of the thermal decomposition reaction of the complex was studied under a non isothermal condition by TG-IR. TG and DTG curves indicate that the complex decomposed in three stages: [Cu(TSSB)(Phen)]·1.5H2O Cu(TSSB)(Phen) Cu(TSSB) CuO The kinetic parameters were obtained from the analysis of TG,DTG cures by OZAWA-Flynn-Wall method, and the activation energy and the value of A of the three stages are 74.98 kJ·mol-1, 286.65 kJ·mol-1, 87.55 kJ·mol-1; 9.66×108 s-1,1.82×1028 s-1, 3.09×103 s-1, respectively.展开更多
