Rb2CsSb is Heusler structured and crystallizes in the cubic Fm-3m space group. Cs(1) is bonded in a 14-coordinate geometry to eight equivalent Rb(1) and six equivalent Sb(1) atoms. Rb(1) is bonded to four equivalent Cs(1) and four equivalent Sb(1) atoms to form a mixture of distorted face, corner, and edge-sharing RbCs4Sb4 tetrahedra. Sb(1) is bonded in a body-centered cubic geometry to six equivalent Cs(1) and eight equivalent Rb(1) atoms.
