Title: Materials Data on Mn2VHO5 by Materials Project

Abstract

VMn2HO5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with six MnO6 octahedra and a cornercorner with one MnO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 38–61°. There are a spread of V–O bond distances ranging from 1.72–1.76 Å. In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with seven MnO6 octahedra and corners with three equivalent MnO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 50–58°. There are a spread of V–O bond distances ranging from 1.69–1.82 Å. There are three inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to five O2- atoms to form MnO5 trigonal bipyramids that share corners with four VO4 tetrahedra and edges with three MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 2.02–2.27 Å. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with five VO4 tetrahedra, edges with four equivalent MnO6 octahedra, and anmore » edgeedge with one MnO5 trigonal bipyramid. There are a spread of Mn–O bond distances ranging from 2.15–2.42 Å. In the third Mn2+ site, Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four VO4 tetrahedra, edges with four MnO6 octahedra, and an edgeedge with one MnO5 trigonal bipyramid. There are a spread of Mn–O bond distances ranging from 2.08–2.33 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one V5+ and two Mn2+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Mn2+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted tetrahedral geometry to three Mn2+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V5+ and one Mn2+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one V5+ and two equivalent Mn2+ atoms. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one V5+ and three Mn2+ atoms. In the seventh O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one V5+ and three Mn2+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V5+ and one Mn2+ atom.« less
