RbK2Bi 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 Bi(1) atoms. K(1) is bonded to four equivalent Rb(1) and four equivalent Bi(1) atoms to form a mixture of distorted edge, face, and corner-sharing KRb4Bi4 tetrahedra. Bi(1) is bonded in a body-centered cubic geometry to six equivalent Rb(1) and eight equivalent K(1) atoms.
