Description
Summary:The Hg atom in the crystal structure of the title compound, (CH6N3)2[HgI4], is tetrahedrally coordinated by four I atoms. The [HgI4]2− ions are interconnected to the [C(NH2)3]+ ions by N—H...I hydrogen bonds, forming a three-dimensional network. The four different observed Hg—I distances [2.760 (2), 2.7762 (15), 2.8098 (14) and 2.833 (2) Å] are consistent with four different 127I NQR frequencies observed, showing the existence of four unique I atoms in the tetraiodidomercurate unit.
