Materials Data on Hg3PClO4 by Materials Project

Abstract

Hg3PO4Cl crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Hg+1.33+ is bonded in a 2-coordinate geometry to three O2- and one Cl1- atom. There are a spread of Hg–O bond distances ranging from 2.29–2.88 Å. The Hg–Cl bond length is 2.78 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.53 Å) and three longer (1.58 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Hg+1.33+ and one P5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to three equivalent Hg+1.33+ and one P5+ atom. Cl1- is bonded in a 3-coordinate geometry to three equivalent Hg+1.33+ atoms.
