摘要：

The heat capacity of deuterated ammonium hexachlorostannate (ND4)2SnCl6 was measured from 5.9 to 347 K by adiabatic calorimetry. The heat capacity is characterized by a λ-shaped anomaly that reaches its maximum Cp,m ≈ 53·R (R = 8.31451 J·K-1·mol-1) at approximately 244 K. The value of ΔSmo for the anomaly is 0.48·R. Values of the standard thermodynamic quantities are tabulated to 350 K. © 1990.
