The crystal structure described by NbRh2 crystallizes in the monoclinic Pm space group. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 9-coordinate geometry to one Rh(4), two equivalent Rh(2), two equivalent Rh(3), and four equivalent Rh(1) atoms. In the second Nb site, Nb(2) is bonded in a 9-coordinate geometry to one Rh(4), two equivalent Rh(1), two equivalent Rh(2), and four equivalent Rh(3) atoms. There are four inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to two equivalent Nb(2) and four equivalent Nb(1) atoms to form distorted RhNb6 cuboctahedra that share corners with four equivalent Rh(1)Nb6 cuboctahedra, corners with six equivalent Rh(2)Nb4 cuboctahedra, edges with two equivalent Rh(1)Nb6 cuboctahedra, edges with three equivalent Rh(2)Nb4 cuboctahedra, edges with four equivalent Rh(3)Nb6 cuboctahedra, faces with two equivalent Rh(1)Nb6 cuboctahedra, and faces with two equivalent Rh(3)Nb6 cuboctahedra. In the second Rh site, Rh(2) is bonded to two equivalent Nb(1) and two equivalent Nb(2) atoms to form distorted RhNb4 cuboctahedra that share corners with six equivalent Rh(1)Nb6 cuboctahedra, corners with six equivalent Rh(3)Nb6 cuboctahedra, edges with two equivalent Rh(2)Nb4 cuboctahedra, edges with three equivalent Rh(1)Nb6 cuboctahedra, and edges with three equivalent Rh(3)Nb6 cuboctahedra. In the third Rh site, Rh(3) is bonded to two equivalent Nb(1) and four equivalent Nb(2) atoms to form distorted RhNb6 cuboctahedra that share corners with four equivalent Rh(3)Nb6 cuboctahedra, corners with six equivalent Rh(2)Nb4 cuboctahedra, edges with two equivalent Rh(3)Nb6 cuboctahedra, edges with three equivalent Rh(2)Nb4 cuboctahedra, edges with four equivalent Rh(1)Nb6 cuboctahedra, faces with two equivalent Rh(1)Nb6 cuboctahedra, and faces with two equivalent Rh(3)Nb6 cuboctahedra. In the fourth Rh site, Rh(4) is bonded in a distorted water-like geometry to one Nb(1) and one Nb(2) atom. is represented by the CIF file [CIF]
