Materials Data on HgMoO4 by Materials Project
HgMoO4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.75–2.29 Å. Hg2+ is bonded in a 2-coordinate geometry to six O2- atoms. There are a spread of Hg–O bond distances ranging from 2.07–2.92 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Mo6+ and two equivalent Hg2+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mo6+ and one Hg2+ atom.
