Materials Data on K2RbSb by Materials Project

K2RbSb is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight equivalent K1+ and six equivalent Sb3- atoms. All Rb–K bond lengths are 3.75 Å. All Rb–Sb bond lengths are 4.33 Å. K1+ is bonded to four equivalent Rb1+ and four equivalent Sb3- atoms to form a mixture of distorted corner, edge, and face-sharing KRb4Sb4 tetrahedra. All K–Sb bond lengths are 3.75 Å. Sb3- is bonded in a body-centered cubic geometry to six equivalent Rb1+ and eight equivalent K1+ atoms.
