| 摘 要： | The crystal of Co（H2O）6]·（Hnip）2·（H2nip）2·（OMA）2·（H2O）8 has been cultured using direct method and characterized by X-ray single crystal diffractometry, elemental analysis and FTIR spectroscopy. It crystallizes in triclinic system, P-1 space group with the cell parameters of a=0.7012（1） nm, b=1.1378（2） nm, c=1.6612（3） nm, α= 84.92（3）°, β=85.19（3）°, γ=85.91（3）°, V= 1.3128（5） nm^3, Z=1, Dc= 1.573 g·cm^-3. Final R indices 1〉2σ（I）] are： R1 =0.0279, wR2=0.0765 while R indices for all data are： R1 =0.0327, wR2=0.0806. The Co coordination octahadra are each surrounded by two Hnip, two H2nip, two DMA and eight water molecules that are linked by hydrogen bonds and π-π stacking interactions. Thermal analyses of DSC and TG-DTG have been performed on the complex to predict its thermal decomposition mechanism and determine the most probable kinetic model function using Kissinger, Ozawa, integral and differential methods.
