Materials Data on K2MnS2 by Materials Project
K2MnS2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. K1+ is bonded in a 5-coordinate geometry to five equivalent S2- atoms. There are a spread of K–S bond distances ranging from 3.20–3.36 Å. Mn2+ is bonded to four equivalent S2- atoms to form edge-sharing MnS4 tetrahedra. All Mn–S bond lengths are 2.44 Å. S2- is bonded in a 7-coordinate geometry to five equivalent K1+ and two equivalent Mn2+ atoms.
