PdAu4Cu3 is Tetraauricupride-derived structured and crystallizes in the tetragonal P4/mmm space group. Pd(1) is bonded to four equivalent Pd(1) and eight equivalent Au(1) atoms to form a mixture of distorted face and corner-sharing PdPd4Au8 cuboctahedra. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 8-coordinate geometry to four equivalent Pd(1) and four equivalent Cu(1) atoms. In the second Au site, Au(2) is bonded in a distorted body-centered cubic geometry to four equivalent Cu(1) and four equivalent Cu(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a body-centered cubic geometry to four equivalent Au(1) and four equivalent Au(2) atoms. In the second Cu site, Cu(2) is bonded in a distorted body-centered cubic geometry to eight equivalent Au(2) atoms.
