Abstract in another language
In order to investigate a possible phase transition at 324 K in the title compound, (NHMe3)2[HgCl4], the crystal structures at 295 and 343 K have been determined, using restrictions of the non-crystallographic site symmetry of the trimethylammonium (TrMA) ions. The hydrogen-bond network, namely N-H...Cl, undergoes a considerable change, by a 38° rotation of one of the TrMA cations about the N-H bond axis. This transition is shown to be a non-symmetry-breaking structural transition, which corresponds to a gradual loss of the orientational order of the TrMA cations.
