The material described by Nb4Rh crystallizes in the orthorhombic Fmmm space group. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 2-coordinate geometry to two equivalent Nb(2) and two equivalent Rh(1) atoms. In the second Nb site, Nb(2) is bonded in a distorted body-centered cubic geometry to two equivalent Nb(1) and six equivalent Nb(2) atoms. Rh(1) is bonded in a 4-coordinate geometry to four equivalent Nb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
