The material structure described by HgWO4 crystallizes in the monoclinic C2/c space group. W(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Hg(1) is bonded in a distorted linear geometry to two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one W(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent W(1) and one Hg(1) atom. is represented by the CIF file [CIF]
