Synthesis, spectroscopic and thermal characterization of Co(II) tetrahydrogen hexaoxoiodate tetrahydrate

  • Deyanka Nikolova


A new cobalt(II) tetrahydrogen hexaoxoiodate tetrahydrate Co(H4IO6)2·4H2O is prepared by crystallization from an acidic aqueous solution. This compound is identified by quantitative analysis, TG, DTA, DSC and IR spectra. A thermal decomposition scheme is proposed. Some phase transitions are identified and the corresponding enthalpy changes are determined.
