Materials Data on Nb4Rh by Materials Project
Nb4Rh crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. there are two inequivalent Nb sites. In the first Nb site, Nb is bonded in a 2-coordinate geometry to two equivalent Nb and two equivalent Rh atoms. Both Nb–Nb bond lengths are 2.89 Å. Both Nb–Rh bond lengths are 2.71 Å. In the second Nb site, Nb is bonded in a distorted body-centered cubic geometry to eight Nb atoms. There are four shorter (2.84 Å) and two longer (2.91 Å) Nb–Nb bond lengths. Rh is bonded in a 12-coordinate geometry to four equivalent Nb atoms.
