NbRh is beta-prime cadmium gold structured and crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. Nb is bonded in a 12-coordinate geometry to eight equivalent Rh atoms. There are a spread of Nb–Rh bond distances ranging from 2.77–2.88 Å. Rh is bonded in a 12-coordinate geometry to eight equivalent Nb atoms.
Nb3Rh crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. Nb is bonded in a 6-coordinate geometry to two equivalent Nb and four equivalent Rh atoms. Both Nb–Nb bond lengths are 2.59 Å. All Nb–Rh bond lengths are 2.90 Å. Rh is bonded to twelve equivalent Nb atoms to form a mixture of face and edge-sharing RhNb12 cuboctahedra.
NbRh is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Nb is bonded to eight equivalent Rh atoms to form a mixture of distorted face, edge, and corner-sharing NbRh8 cuboctahedra. All Nb–Rh bond lengths are 2.81 Å. Rh is bonded to eight equivalent Nb atoms to form a mixture of distorted face, edge, and corner-sharing RhNb8 cuboctahedra.
Rh3Nb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional.

NbRh is Tetraauricupride-like structured and crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are two inequivalent Nb sites. In the first Nb site, Nb is bonded in a 12-coordinate geometry to eight Rh atoms. There are a spread of Nb–Rh bond distances ranging from 2.76–2.88 Å. In the second Nb site, Nb is bonded to eight Rh atoms to form a mixture of distorted edge, corner, and face-sharing NbRh8 cuboctahedra. There are four shorter (2.80 Å) and four longer (2.84 Å) Nb–Rh bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded to eight Nb atoms to form a mixture of distorted edge, corner, and face-sharing RhNb8 cuboctahedra. In the second Rh site, Rh is bonded in a 12-coordinate geometry to eight Nb atoms.
