The compound described by NdRh3 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 12-coordinate geometry to three equivalent Rh(4) and nine equivalent Rh(1) atoms. In the second Nd site, Nd(2) is bonded in a distorted hexagonal planar geometry to three equivalent Rh(2), three equivalent Rh(3), and twelve equivalent Rh(1) atoms. There are four inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to two equivalent Nd(2), three equivalent Nd(1), one Rh(2), one Rh(3), one Rh(4), and four equivalent Rh(1) atoms to form distorted RhNd5Rh7 cuboctahedra that share corners with two equivalent Rh(4)Nd6Rh6 cuboctahedra, corners with fifteen equivalent Rh(1)Nd5Rh7 cuboctahedra, edges with eight equivalent Rh(1)Nd5Rh7 cuboctahedra, faces with three equivalent Rh(4)Nd6Rh6 cuboctahedra, and faces with eleven equivalent Rh(1)Nd5Rh7 cuboctahedra. In the second Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent Nd(2) and six equivalent Rh(1) atoms. In the third Rh site, Rh(3) is bonded in a 9-coordinate geometry to three equivalent Nd(2) and six equivalent Rh(1) atoms. In the fourth Rh site, Rh(4) is bonded to six equivalent Nd(1) and six equivalent Rh(1) atoms to form RhNd6Rh6 cuboctahedra that share corners with twelve equivalent Rh(1)Nd5Rh7 cuboctahedra, edges with six equivalent Rh(4)Nd6Rh6 cuboctahedra, and faces with eighteen equivalent Rh(1)Nd5Rh7 cuboctahedra. is represented by the CIF file [CIF]
