Materials Data on K2ZnS2 by Materials Project
K2ZnS2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six equivalent S2- atoms. There are a spread of K–S bond distances ranging from 3.20–3.61 Å. Zn2+ is bonded to four equivalent S2- atoms to form edge-sharing ZnS4 tetrahedra. All Zn–S bond lengths are 2.40 Å. S2- is bonded in a 2-coordinate geometry to six equivalent K1+ and two equivalent Zn2+ atoms.
