Nd3Au4 crystallizes in the trigonal R-3 space group. Nd(1) is bonded in a 9-coordinate geometry to one Au(2), one Au(3), and seven equivalent Au(1) atoms. There are three inequivalent Au sites. In the first Au site, Au(2) is bonded to six equivalent Nd(1) atoms to form distorted face-sharing AuNd6 octahedra. In the second Au site, Au(1) is bonded in a 7-coordinate geometry to seven equivalent Nd(1) atoms. In the third Au site, Au(3) is bonded to six equivalent Nd(1) atoms to form distorted face-sharing AuNd6 octahedra.
