The material structure described by K2RbSb is Heusler structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded in a 14-coordinate geometry to eight equivalent K(1) and six equivalent Sb(1) atoms. K(1) is bonded to four equivalent Rb(1) and four equivalent Sb(1) atoms to form a mixture of distorted corner, edge, and face-sharing KRb4Sb4 tetrahedra. Sb(1) is bonded in a body-centered cubic geometry to six equivalent Rb(1) and eight equivalent K(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
