The heat capacity, thermogravimetry, differential thermal and standard heat of combustion of the complex were measured. In the temperature range of 78 ~ 370 K, the heat capacity was measured by high-precision automatic adiabatic calorimeter. The polynomial equation of heat capacity to temperature of the computer was fitted as follows: Cp = 140 7.0 8 + 75 1.6 7X +170. 17X2 +89.5 9X3- 76 .11X4 and Cp = 1317.99 + 6 33.0 5 X +16 3.82 X2 +15 0 .2 3X3-86 .1X4, [Er2 (Pro) 6 (H2O) 4] (ClO4) 6 The Cp-T curve has a melting peak with a calculated melting point of 35.5.55 K, a melting entropy of 6 9.5 42 J / (K mol) and a melting enthalpy of 2 472 581 J / mol. TG and DTA techniques to study the thermal decomposition process, preliminary analysis of the decomposition mechanism of the complex. The heat of combustion experiment shows that their standard heat of combustion is 1772 0 .41k J / mol and 1810 1.6 5 k J / mol respectively
