Compounds of the general formula, C6H5CnH2nNH3)2MCl4, where n = 1 to 10; M = Cd, Cu, Zn, and Co; were prepared and characterized by differential scanning calorimetry. All of the compounds prepared with n > 1 were observed to undergo solid-solid phase transitions and the high entropies of the solid-solid phase transitions indicate that there is a considerable amount of disorder in the high-temperature
通式为C 6 H 5 C n H 2 n NH 3)2 M Cl 4的化合物,其中n= 1至10;M = Cd,Cu,Zn和Co; 制备并通过差示扫描量热法表征。用n制备的所有化合物观察到> 1经历了固-固相变,并且固-固相变的高熵表明在高温相中存在相当多的无序。热力学结果的相似性将化合物分为两组:Cd和Cu衍生物以及Co和Zn衍生物。每组内以及各组之间的趋势可归因于苯基基团堆积对热力学行为的影响。
