Its crystal structure was determined and refined down to R=0.0549 and Rw=0.1303. The examination of the structure shows a layer arrangement parallel to the b axis: the anionic layer may be considered as a succession of layers built up distorted triangular bipyramid [HgCl3]−. The crystal packing is governed by means of the ionic N-H Cl hydrogen bonds, forming a three dimensional network. DSC measurement reveals a transition at T=418K and dielectric measurements were performed to discuss the mechanism of the phase transition. The evolution of dielectric constant as a function of temperature of single crystal has been investigated in order to determine some related parameters.
