Materials Data on Hg2ClO by Materials Project

Hg2OCl crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Hg+1.50+ sites. In the first Hg+1.50+ site, Hg+1.50+ is bonded in a 3-coordinate geometry to two equivalent O2- and two equivalent Cl1- atoms. There are one shorter (2.30 Å) and one longer (2.56 Å) Hg–O bond lengths. There are one shorter (2.61 Å) and one longer (3.31 Å) Hg–Cl bond lengths. In the second Hg+1.50+ site, Hg+1.50+ is bonded in a 2-coordinate geometry to two equivalent O2- and two equivalent Cl1- atoms. Both Hg–O bond lengths are 2.32 Å. Both Hg–Cl bond lengths are 2.89 Å. In the third Hg+1.50+ site, Hg+1.50+ is bonded in a distorted linear geometry to two equivalent O2- and four equivalent Cl1- atoms. Both Hg–O bond lengths are 2.07 Å. There are two shorter (3.25 Å) and two longer (3.40 Å) Hg–Cl bond lengths. O2- is bonded to four Hg+1.50+ atoms to form a mixture of distorted edge and corner-sharing OHg4 tetrahedra. Cl1- is bonded in a 2-coordinate geometry to five Hg+1.50+ atoms.
