Materials Data on HgClO3 by Materials Project
HgO3Cl crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight HgO3Cl clusters. Hg is bonded in a distorted single-bond geometry to one O atom. The Hg–O bond length is 2.25 Å. There are three inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.49 Å. In the second O site, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.48 Å. In the third O site, O is bonded in a water-like geometry to one Hg and one Cl atom. The O–Cl bond length is 1.59 Å. Cl is bonded in a trigonal non-coplanar geometry to three O atoms.
