Nb Bi Rh Rh
NbRh2Bi is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NbRh2Bi clusters. Nb(1) is bonded in an L-shaped geometry to two equivalent Rh(1) atoms. Both Nb(1)-Rh(1) bond lengths are 0.36 Å. Rh(1) is bonded in an L-shaped geometry to one Nb(1) and one Bi(1) atom. The Rh(1)-Bi(1) bond length is 0.36 Å. Bi(1) is bonded in a distorted L-shaped geometry to two equivalent Rh(1) atoms.
