RbZn4P3 crystallizes in the tetragonal P4/mmm space group. Rb(1) is bonded in a body-centered cubic geometry to eight equivalent P(2) atoms. Zn(1) is bonded to two equivalent P(1) and two equivalent P(2) atoms to form a mixture of edge and corner-sharing ZnP4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded in a body-centered cubic geometry to eight equivalent Zn(1) atoms. In the second P site, P(2) is bonded in a 8-coordinate geometry to four equivalent Rb(1) and four equivalent Zn(1) atoms.
