The material structure described by Nd2Rh12P7 crystallizes in the trigonal P-3 space group. Nd(1) is bonded to three equivalent Rh(2), nine equivalent Rh(1), and six equivalent P(2) atoms to form distorted NdP6Rh12 cuboctahedra that share corners with three equivalent P(1)Rh6 octahedra, edges with six equivalent Nd(1)P6Rh12 cuboctahedra, and faces with two equivalent Nd(1)P6Rh12 cuboctahedra. The corner-sharing octahedral tilt angles are 26°. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 6-coordinate geometry to three equivalent Nd(1) and four equivalent P(2) atoms. In the second Rh site, Rh(2) is bonded in a 4-coordinate geometry to one Nd(1), one P(1), and three equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to six equivalent Rh(2) atoms to form distorted PRh6 octahedra that share corners with six equivalent Nd(1)P6Rh12 cuboctahedra. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Nd(1), three equivalent Rh(2), and four equivalent Rh(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
