The title compound [ Co （phendione） （ SO4 ） （ H2O） ]·5H2O aqueous solution and characterized by elemental analysis, IR spectroscopy, results indicate that in the compound the cobalt atom is four coordinated and thermal analyses. The by two nitrogen atoms from phendione and two oxygen atoms from water molecules and vitriolic ion, respectively. The thermal decomposition mechanism of the compound was also discussed based on the TG-DTG curves and the finally product of thermal decomposition was CoO.
