The compound described by Nb4Pd 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 Pd(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. Pd(1) is bonded to four equivalent Nb(1) atoms to form distorted edge-sharing PdNb4 cuboctahedra. is represented by the CIF card [CIF]
