Materials Data on K3InP2 by Materials Project

Abstract

K3InP2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 4-coordinate geometry to four equivalent P3- atoms. There are a spread of K–P bond distances ranging from 3.27–3.67 Å. In the second K1+ site, K1+ is bonded in a 4-coordinate geometry to four equivalent P3- atoms. All K–P bond lengths are 3.27 Å. In3+ is bonded to four equivalent P3- atoms to form edge-sharing InP4 tetrahedra. All In–P bond lengths are 2.67 Å. P3- is bonded in a 8-coordinate geometry to six K1+ and two equivalent In3+ atoms.
