Bis(guanidinium) tetra­iodidomercurate(II)

The Hg atom in the crystal structure of the title compound, (CH(6)N(3))(2)[HgI(4)], is tetra­hedrally coordinated by four I atoms. The [HgI(4)](2−) ions are inter­connected to the [C(NH(2))(3)](+) ions by N—H⋯I hydrogen bonds, forming a three-dimensional network. The four different observed Hg—I dis...

Sumario:The Hg atom in the crystal structure of the title compound, (CH(6)N(3))(2)[HgI(4)], is tetra­hedrally coordinated by four I atoms. The [HgI(4)](2−) ions are inter­connected to the [C(NH(2))(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 (127)I NQR frequencies observed, showing the existence of four unique I atoms in the tetra­iodidomercurate unit.
