Its structure was determined by single crystal X-ray diffraction method. The complex, C38H50Cl2N2O2Zn, crystallizes in the orthorhombic system, space group Aba2 with a=1.381 7(3), b=2.275 0(5), c=1.145 0(2) nm, V=3.599(1) nm3, Z=4, Mr=653.79, F(000)=1 496, Dc=1.301 kg·m-3, μ(Mo Kα)=0.866 mm-1. The kinetic parameters were obtained from the analysis of TG curve by integral methods. The functions of thermal decomposition reaction mechanism are: F(α)=[1-(1-α)1/3]2, and kinetic compensation effect equation lnA=0.019 1E-0.142 7. CCDC: 253297.展开更多

Crystal data: orthorhombic system with space group Pnna and unite cell parameters: a=2.0645(3)nm, b=1.3484(2)nm, c=0.8204(1)nm; V=2.2838(6)nm3, Z=4, Dcald=1.726 g· cm- 3, μ =1.193 mm- 1, F(000)=1212, Gof=1.045, Δ ρ =339～ - 348 e· nm- 3, the final R is 0.0295. In the molecule of the complex, Co? ion is six coordinate to form a distorted octahedron. The N atom and the carboxyl group of pyridine 2,6 dicarboxylic acid are coordinated with the central ions. One of the carboxyl groups of the pyridine 2,6 dicarboxylic acid connect K? and Co? . The com pound possesses approximate C2 symmetry. The compounds form a three dimensional network of infinite length connection with crystal waters, potassium ions and hydrogen bonds. The result of kinetics of thermal decomposition indicated that the compound decomposition takes place in two steps. CCDC: 207078.展开更多
