Conclusions

  1. 1.

    The true heat capacity of tetrammine chloroplatinate is measured for the temperature range 13–300°K. A λ-type anomaly is observed on the curve of heat capacity against temperature in the region 150–175°K.

     
  2. 2.

    The heat contents, entropies and free energies of formation at 298.15°K are calculated for the following compounds: [Pt(NH3)4]Cl2, cis-[Pt(NH3)2Cl2] and trans-[Pt(NH3)2Cl2].

     
  3. 3.

    We calculated the free energies for the reactions of decomposition of the tetramine with the formation of the cis and trans diamine. The difference between the free energies, equal to 3.28 kcal/mole, can be considered as the thermal characteristic of the trans effect.
