HgCN3H3 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four HgCN3H3 clusters. Hg(1) is bonded in a linear geometry to one C(1) and one N(3) atom. C(1) is bonded in a distorted tetrahedral geometry to one Hg(1), one H(1), one H(2), and one H(3) atom. There are three inequivalent N sites. In the first N site, N(1) is bonded in a linear geometry to one N(2) and one N(3) atom. In the second N site, N(2) is bonded in a single-bond geometry to one N(1) atom. In the third N site, N(3) is bonded in a bent 120 degrees geometry to one Hg(1) and one N(1) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(1) atom.
