The material described by Hg7O3Cl2 crystallizes in the orthorhombic Pbcm space group. There are five inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted single-bond geometry to two equivalent O(2) atoms. In the second Hg site, Hg(2) is bonded in a distorted L-shaped geometry to one O(1) and one O(2) atom. In the third Hg site, Hg(3) is bonded in a single-bond geometry to one O(1) atom. In the fourth Hg site, Hg(4) is bonded in a distorted L-shaped geometry to one O(1) and one Cl(2) atom. In the fifth Hg site, Hg(5) is bonded in a linear geometry to two equivalent O(2) and two equivalent Cl(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a tetrahedral geometry to one Hg(3), one Hg(4), and two equivalent Hg(2) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Hg(2), one Hg(5), and two equivalent Hg(1) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a single-bond geometry to one Hg(4) atom. In the second Cl site, Cl(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Hg(5) atoms. is represented by the CIF file [CIF]
