Materials Data on Mn3V2Si3 by Materials Project

Abstract

V2Mn3Si3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. V3+ is bonded to six Si4- atoms to form a mixture of distorted corner, edge, and face-sharing VSi6 octahedra. The corner-sharing octahedral tilt angles are 39°. All V–Si bond lengths are 2.51 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in a distorted pentagonal planar geometry to five Si4- atoms. There are a spread of Mn–Si bond distances ranging from 2.39–2.54 Å. In the second Mn2+ site, Mn2+ is bonded in a distorted pentagonal planar geometry to five Si4- atoms. There are a spread of Mn–Si bond distances ranging from 2.38–2.54 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 9-coordinate geometry to four equivalent V3+ and five Mn2+ atoms. In the second Si4- site, Si4- is bonded in a 9-coordinate geometry to four equivalent V3+ and five Mn2+ atoms.
