Ethyl-enediammonium tetra-bromido-mercurate(II) monohydrate.

ABSTRACT: The Hg(II) atoms in the crystal structure of the title compound, (C(2)H(10)N(2))[HgBr(4)]·H(2)O, are tetra-hedrally coordinated by four Br atoms and the resulting [HgBr(4)](2-) ions are inter-connected to the [NH(3)-CH(2)-CH(2)-NH(3)](2+) ions and water mol-ecules by N-H⋯Br and O-H⋯Br bonds, forming a three-dimensional network. N-H⋯O inter-actions are also present. The observed three different Hg-Br distances of 2.5597 (6), 2.6862 (8) and 2.6923 (8) Å in the tetra-bromo-mercurate unit are due to the connection of Br atoms to different numbers of H atoms. The Hg, O and two Br atoms are located on a crystallographic mirror plane. The cation has symmetry with the center of the C-C bond lying on a crystallographic center of inversion.
