Solid State Synthesis and Characteristies of the Polyamine Metal Complexes in Room Temperature
Abstract：{Cu{OC(NH2) 2}4Cl2和{Zn[OC(NH2)2]4}(C4H6O4) were synthesized by the room tempreature solid state synthesis with the material of copper chloride, zinc acetate and urea. Their composition, structure, and thermostability were characterized by the chemical analysis, IR, and TG—DSC, DSC. The results showed that the mole ratio of copper salt and urea was 1:4, the molecular formula is {Cu{OC(NH2) 2}4Cl2, the coordination bond is the oxygen of the carbonyl, the thermostability of coordinated urea was lifted, the enthalpy during melting down is 52.36J/g, the melting point is 98.51℃, Ea=178.28 kJ/mol, k0=1.52*1018mol/(min*L) in the second decomposition period. the mole ratio of zinc salt and urea was 1:4, the molecular formula is{Zn[OC(NH2)2]4}(C4H6O4), the coordination bond is the oxygen of the carbonyl, the thermostability of coordinated urea was reduced, the enthalpy during melting down is 84.49J/g, the melting point is 111.14℃, Ea=167.97kJ/mol，k0=5.86*1020mol/(min*L) in the decomposition period.
