摘要：
The heat capacity of the Fe(prtrz)(3)Br-2 . 4H(2)O (I) and Fe(prtrz)(3)(CF3SO3)(2) . 5H(2)O (II) complexes with the (1)A(1) double left right arrow T-5(2) spin transition was studied by vacuum adiabatic calorimetry over the temperature range 80330 K. The spin transitions in these compounds were found to be first-order phase transitions, T-tr = 253.90 and 198.0 K for I and II, respectively, which was in agreement with magnetochemical data. The thermodynamic parameters of the phase transitions in these complexes were determined.
