The crystal structure described by Hg3Sb3Se8N(CH3)2 is Germanium disuphide-derived structured and crystallizes in the orthorhombic Aem2 space group. The structure consists of four dimethylamine molecules inside a Hg3Sb3Se8 framework. In the Hg3Sb3Se8 framework, there are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded to two equivalent Se(2) and two equivalent Se(5) atoms to form corner-sharing HgSe4 tetrahedra. In the second Hg site, Hg(2) is bonded to one Se(2), one Se(3), one Se(4), and one Se(5) atom to form corner-sharing HgSe4 tetrahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted T-shaped geometry to one Se(1), one Se(2), and one Se(3) atom. In the second Sb site, Sb(2) is bonded in a distorted T-shaped geometry to one Se(4) and two equivalent Se(5) atoms. There are five inequivalent Se sites. In the first Se site, Se(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Hg(2) and one Sb(2) atom. In the second Se site, Se(5) is bonded in a distorted trigonal non-coplanar geometry to one Hg(1), one Hg(2), and one Sb(2) atom. In the third Se site, Se(1) is bonded in a water-like geometry to two equivalent Sb(1) atoms. In the fourth Se site, Se(2) is bonded in a distorted T-shaped geometry to one Hg(1), one Hg(2), and one Sb(1) atom. In the fifth Se site, Se(3) is bonded in an L-shaped geometry to one Hg(2) and one Sb(1) atom. is represented by the CIF file [CIF]
