HgNOI3 crystallizes in the monoclinic Cc space group. Hg(1) is bonded to one I(2), one I(3), and two equivalent I(1) atoms to form corner-sharing HgI4 tetrahedra. N(1) is bonded in a distorted single-bond geometry to one O(1), one I(2), and one I(3) atom. O(1) is bonded in a single-bond geometry to one N(1) atom. There are three inequivalent I sites. In the first I site, I(1) is bonded in a water-like geometry to two equivalent Hg(1) atoms. In the second I site, I(2) is bonded in a bent 120 degrees geometry to one Hg(1) and one N(1) atom. In the third I site, I(3) is bonded in a water-like geometry to one Hg(1) and one N(1) atom.
HgNOI3 crystallizes in the monoclinic Cc space group. Hg(1) is bonded to one I(2), one I(3), and two equivalent I(1) atoms to form corner-sharing HgI4 tetrahedra. The Hg(1)-I(2) bond length is 2.82 Å. The Hg(1)-I(3) bond length is 2.84 Å. There is one shorter (2.87 Å) and one longer (2.91 Å) Hg(1)-I(1) bond length. N(1) is bonded in a distorted single-bond geometry to one O(1), one I(2), and one I(3) atom. The N(1)-O(1) bond length is 1.15 Å. The N(1)-I(2) bond length is 2.78 Å. The N(1)-I(3) bond length is 2.66 Å. O(1) is bonded in a single-bond geometry to one N(1) atom. There are three inequivalent I sites.
