The material described by (NH4)4HgBr6 is Silicon tetrafluoride-derived structured and crystallizes in the orthorhombic Pnnm space group. The structure is zero-dimensional and consists of eight ammonium molecules, four hydrogen bromide atoms, and two HgBr4 clusters. In each HgBr4 cluster, Hg(1) is bonded in a distorted linear geometry to two equivalent Br(2) and two equivalent Br(3) atoms. There are two inequivalent Br sites. In the first Br site, Br(2) is bonded in a distorted single-bond geometry to one Hg(1) atom. In the second Br site, Br(3) is bonded in a single-bond geometry to one Hg(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
