The material structure described by Zr2Rh12P7 crystallizes in the trigonal P-3 space group. Zr(1) is bonded to six equivalent Rh(1) and six equivalent P(2) atoms to form distorted ZrP6Rh6 cuboctahedra that share corners with twelve equivalent Rh(2)P4 tetrahedra, edges with three equivalent Rh(2)P4 tetrahedra, and faces with two equivalent Zr(1)P6Rh6 cuboctahedra. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 6-coordinate geometry to two equivalent Zr(1) and four equivalent P(2) atoms. In the second Rh site, Rh(2) is bonded to one P(1) and three equivalent P(2) atoms to form distorted RhP4 tetrahedra that share corners with four equivalent Zr(1)P6Rh6 cuboctahedra, corners with seven equivalent Rh(2)P4 tetrahedra,  an edgeedge with one Zr(1)P6Rh6 cuboctahedra, and edges with two equivalent Rh(2)P4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 6-coordinate geometry to six equivalent Rh(2) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Zr(1), three equivalent Rh(2), and four equivalent Rh(1) atoms. is represented by the CIF file [CIF]
