The compound described by Y2Rh12P7 crystallizes in the trigonal P-3 space group. Y(1) is bonded to six equivalent Rh(1) and six equivalent P(2) atoms to form distorted YP6Rh6 cuboctahedra that share corners with twelve equivalent Rh(2)P4 tetrahedra, edges with three equivalent Rh(2)P4 tetrahedra, and faces with two equivalent Y(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 Y(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 Y(1)P6Rh6 cuboctahedra, corners with seven equivalent Rh(2)P4 tetrahedra,  an edgeedge with one Y(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 distorted octahedral geometry to six equivalent Rh(2) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Y(1), three equivalent Rh(2), and four equivalent Rh(1) atoms. is represented by the CIF file [CIF]
