title: Materials Data on MnAsO5 by Materials Project

description: MnAsO5 crystallizes in the monoclinic P2_1 space group. The structure is two-dimensional and consists of two MnAsO5 sheets oriented in the (0, 1, 0) direction. there are four inequivalent Mn7+ sites. In the first Mn7+ site, Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with five AsO4 tetrahedra and edges with two MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.81–2.12 Å. In the second Mn7+ site, Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with five AsO4 tetrahedra and edges with two MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.92–2.12 Å. In the third Mn7+ site, Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with five AsO4 tetrahedra and edges with two MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.71–2.08 Å. In the fourth Mn7+ site, Mn7+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with five AsO4 tetrahedra and edges with two MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.71–2.10 Å. There are four inequivalent As3+ sites. In the first As3+ site, As3+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with five MnO6 octahedra. The corner-sharing octahedra tilt angles range from 52–63°. There are a spread of As–O bond distances ranging from 1.72–1.77 Å. In the second As3+ site, As3+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with five MnO6 octahedra. The corner-sharing octahedra tilt angles range from 50–63°. There are a spread of As–O bond distances ranging from 1.72–1.78 Å. In the third As3+ site, As3+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with five MnO6 octahedra. The corner-sharing octahedra tilt angles range from 49–56°. There are a spread of As–O bond distances ranging from 1.68–1.81 Å. In the fourth As3+ site, As3+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with five MnO6 octahedra. The corner-sharing octahedra tilt angles range from 46–55°. There are a spread of As–O bond distances ranging from 1.67–1.81 Å. There are twenty inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one As3+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one As3+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to two Mn7+ and one As3+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Mn7+ and one As3+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Mn7+ and one As3+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Mn7+ and one As3+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn7+ and one As3+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn7+ and one As3+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn7+ and one As3+ atom. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn7+ and one As3+ atom.
