The compositions of complexes were determined as, by chemical and elemental analyses, Mn2CI2, Mn2Cl2, Cu2Cl2-2H2O, Cu(NO3)2-H2O, Cu(CH3COO)2, Zn2Cl2, Zn2(NO3)2-4H2O,ZnSO4 and Zn4(NO3)2, respectively. These complexes were characterized by IR,'H NMR and XPS. The crystal structures of these complexes were determined by single crystal X-ray diffraction techniques. The thermstability of the complexes was investigated by TG-DTG and the processes of their thermal decomposition were speculated. The constant-volume combustion energies of complexes, cU, were determined by a precision rotating bomb calorimeter at 298.15 K. Their standard enthalpies of formation, Hm, were calculated respectively. Finally, their biological activity was researched after the bactericidal activity was determined by selection of 1-2 bacteria.
