摘要：

The heat capacity of methylammonium-d//6 hexachlorostannate has been measured between 13 and 300 K. A peak due to the phase transition occurred at (154. 96 plus or minus 0. 06) K. Critical properties of the transition were characterized by detailed measurement around T//c. Models of disorder that carry large enough entropy to explain the experimental transition entropy 21. 8 J K** minus **1 mol** minus **1 are proposed, with particular attention paid to the symmetry of the two phases.
