Materials Data on KHg(PO3)3 by Materials Project
KHg(PO3)3 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.71–3.07 Å. Hg2+ is bonded to six O2- atoms to form HgO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Hg–O bond distances ranging from 2.31–2.52 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent HgO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 51–56°. There are a spread of P–O bond distances ranging from 1.50–1.64 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent HgO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 54–58°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent HgO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 47–56°. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+, one Hg2+, and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Hg2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Hg2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Hg2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Hg2+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+, one Hg2+, and one P5+ atom.
