Materials Data on Mn(SO6)2 by Materials Project

Abstract

Mn(SO5)2O2 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of eight water molecules and two Mn(SO5)2 sheets oriented in the (0, 0, 1) direction. In each Mn(SO5)2 sheet, Mn is bonded to six O atoms to form MnO6 octahedra that share corners with four equivalent SO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 1.79–2.02 Å. S is bonded to four O atoms to form SO4 tetrahedra that share corners with two equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 52–54°. There are a spread of S–O bond distances ranging from 1.45–1.53 Å. There are five inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to one Mn and one S atom. In the second O site, O is bonded in a single-bond geometry to one S atom. In the third O site, O is bonded in a single-bond geometry to one S atom. In the fourth O site, O is bonded in a bent 120 degrees geometry to one Mn and one S atom. In the fifth O site, O is bonded in a single-bond geometry to one Mn atom.
