| Abstract: The title complex Cu[C5H3N(CCH3=N-C6H5)2]2(PF6)2 has been synthesized by reaction of Schiff base C5H3N(CCH3=N-C6H5)2 and cupric sulfate in toluene solution. The crystal structure was determined by X-ray diffraction method and the chemical formula weight of the complex is 1041.85. The crystal structure belongs to triclinic system with space group P1 and cell parameters: a=12.6470(10)?, b=14.123(2)?, c=15.613(2)?;α=66.150(10)°,β=79.470(10)°,γ=78.290(10)°, V=2481.6(5)?3, Z=2, Dc=1.394Mg·m-3 and F(000)=1064. The final R[I >2σ(I)]:R1=0.0668, wR2=0.1927; R(all data): R1=0.1133, wR2=0.2357. The Cu(Ⅱ) was coordinated by six nitrogen, at the same time the Cu(Ⅱ) formed a distorted octahedron, besides the angles and planes of this compound were discussed . The result of kinetics of the thermal decomposition indicated that the first step of it is 2 series chemical reactions, the function of machanism is f(a)=(1-a)2, and the activation energy is 144.64E/kJ. CCDC: 180872. |
