The crystal structure described by HgPO4 is Iron carbide-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two HgPO4 clusters. Hg(1) is bonded in a 1-coordinate geometry to two equivalent O(1) atoms. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Hg(1) and one P(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one P(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one P(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one P(1) atom. is represented by the CIF file [CIF]
