Al Rh Au Au
RhAu2Al crystallizes in the triclinic P1 space group. Rh(1) is bonded in a 2-coordinate geometry to one Au(1), two equivalent Au(2), and one Al(1) atom. The Rh(1)-Au(1) bond length is 1.56 Å. There is one shorter (2.28 Å) and one longer (2.46 Å) Rh(1)-Au(2) bond length. The Rh(1)-Al(1) bond length is 1.66 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 4-coordinate geometry to one Rh(1), one Au(2), and two equivalent Al(1) atoms. The Au(1)-Au(2) bond length is 1.81 Å. There is one shorter (2.42 Å) and one longer (2.76 Å) Au(1)-Al(1) bond length. In the second Au site, Au(2) is bonded in a 5-coordinate geometry to two equivalent Rh(1), one Au(1), and two equivalent Al(1) atoms. There is one shorter (2.69 Å) and one longer (2.77 Å) Au(2)-Al(1) bond length. Al(1) is bonded in a 1-coordinate geometry to one Rh(1), two equivalent Au(1), and two equivalent Au(2) atoms.
