Materials Data on Hg2PO3F by Materials Project
Hg2PO3F crystallizes in the orthorhombic Ibam space group. The structure is two-dimensional and consists of two Hg2PO3F sheets oriented in the (0, 0, 1) direction. Hg1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Hg–O bond distances ranging from 2.38–2.55 Å. P5+ is bonded in a tetrahedral geometry to three O2- and one F1- atom. There is one shorter (1.52 Å) and two longer (1.54 Å) P–O bond length. The P–F bond length is 1.60 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Hg1+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Hg1+ and one P5+ atom. F1- is bonded in a single-bond geometry to one P5+ atom.
