Title: Materials Data on K2Mn(SO6)2 by Materials Project

Abstract

K2Mn(SO6)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. K is bonded in a 6-coordinate geometry to nine O atoms. There are a spread of K–O bond distances ranging from 2.89–3.32 Å. There are two inequivalent Mn sites. In the first Mn site, Mn is bonded to six O atoms to form MnO6 octahedra that share corners with two equivalent SO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 1.87–1.89 Å. In the second Mn site, Mn is bonded to six O atoms to form MnO6 octahedra that share corners with two equivalent SO4 tetrahedra. There is four shorter (1.84 Å) and two longer (1.98 Å) Mn–O bond length. There are two inequivalent S sites. In the first S site, S is bonded to four O atoms to form SO4 tetrahedra that share a cornercorner with one MnO6 octahedra. The corner-sharing octahedral tilt angles are 22°. There is three shorter (1.47 Å) and one longer (1.58 Å) S–O bond length. In the second S site, S is bonded to four O atoms to form SO4 tetrahedra that share a cornercorner with one MnO6 octahedra. The corner-sharing octahedral tilt angles are 45°. There is threemore » shorter (1.47 Å) and one longer (1.56 Å) S–O bond length. There are nine inequivalent O sites. In the first O site, O is bonded in a 2-coordinate geometry to two equivalent K, one Mn, and one S atom. In the second O site, O is bonded in a distorted single-bond geometry to two equivalent K and one S atom. In the third O site, O is bonded in a distorted single-bond geometry to one K and one Mn atom. In the fourth O site, O is bonded in a distorted single-bond geometry to two equivalent K and one Mn atom. In the fifth O site, O is bonded in a single-bond geometry to two equivalent K and one Mn atom. In the sixth O site, O is bonded in a distorted single-bond geometry to one K and one S atom. In the seventh O site, O is bonded in a distorted single-bond geometry to one K and one S atom. In the eighth O site, O is bonded in a bent 150 degrees geometry to two equivalent K, one Mn, and one S atom. In the ninth O site, O is bonded in a distorted trigonal planar geometry to two equivalent K and one S atom.« less
