Guanidinium tetra-bromidomercurate(II).


ABSTRACT: The Hg atoms in the crystal structure of the title compound, (CH(6)N(3))(2)[HgBr(4)], are tetra-hedrally coordinated by four Br atoms and the resulting [HgBr(4)](2-) tetra-hedral ions are linked to the [C(NH(2))(3)](+) ions by bromine-hydrogen bonds, forming a three-dimensional network. In the structure, the anions are located on special positions. The two different Hg?Br distances of 2.664?(1) and 2.559?(1)?Å observed in the tetra-bromidomercurate unit are due to the connection of Br atoms to different number of H atoms.
