RhAu3 crystallizes in the triclinic P1 space group. Rh(1) is bonded in a 12-coordinate geometry to two equivalent Rh(1), two equivalent Au(1), four equivalent Au(2), and four equivalent Au(3) atoms. Both Rh(1)-Rh(1) bond lengths are 2.85 Å. There is one shorter (2.63 Å) and one longer (3.35 Å) Rh(1)-Au(1) bond length. There are a spread of Rh(1)-Au(2) bond distances ranging from 2.53-3.45 Å. There are a spread of Rh(1)-Au(3) bond distances ranging from 2.67-3.08 Å. There are three inequivalent Au sites. In the first Au site, Au(1) is bonded in a 12-coordinate geometry to two equivalent Rh(1), two equivalent Au(1), four equivalent Au(2), and four equivalent Au(3) atoms. Both Au(1)-Au(1) bond lengths are 2.85 Å. There are a spread of Au(1)-Au(2) bond distances ranging from 2.51-3.23 Å. There are a spread of Au(1)-Au(3) bond distances ranging from 2.39-3.35 Å. In the second Au site, Au(2) is bonded in a 12-coordinate geometry to four equivalent Rh(1), two equivalent Au(2), two equivalent Au(3), and four equivalent Au(1) atoms. Both Au(2)-Au(2) bond lengths are 2.85 Å. There is one shorter (2.51 Å) and one longer (3.26 Å) Au(2)-Au(3) bond length. In the third Au site, Au(3) is bonded in a 12-coordinate geometry to four equivalent Rh(1), two equivalent Au(2), two equivalent Au(3), and four equivalent Au(1) atoms. Both Au(3)-Au(3) bond lengths are 2.85 Å.
