The compound described by HgNO4 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two HgNO4 clusters. Hg(1) is bonded in a 3-coordinate geometry to one O(4) and two equivalent O(1) atoms. N(1) is bonded in a trigonal planar geometry to 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 water-like geometry to two equivalent Hg(1) atoms. In the second O site, O(2) is bonded in a single-bond geometry to one N(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one N(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to one Hg(1) and one N(1) atom. is represented by the CIF card [CIF]
