Molar heat capacity and thermodynamic properties of crystalline Ho(Asp)Cl-2 center dot 6H(2)O

The molar heat capacity, C (p,m), of a complex of holmium chloride coordinated with L-aspartic acid, Ho(Asp)Cl-2 center dot 6H(2)O, was measured from 80 to 397 K with an automated adiabatic calorimeter. The thermodynamic functions H (T)-H (298.15) and S (T)-S (298.15) were derived from 80 to 395 K with temperature interval of 5 K. The thermal stability of the complex was investigated by differential scanning calorimeter (DSC) and thermogravimetric (TG) technique, and the mechanism of thermal decomposing of the complex was determined based on the structure and the thermal analysis experiment
