CrPtAu2 crystallizes in the triclinic P1 space group. Cr(1) is bonded in a 2-coordinate geometry to four equivalent Pt(1), one Au(1), and one Au(2) atom. There are a spread of Cr(1)-Pt(1) bond distances ranging from 2.24-3.31 Å. The Cr(1)-Au(1) bond length is 2.76 Å. The Cr(1)-Au(2) bond length is 2.17 Å. Pt(1) is bonded in a 12-coordinate geometry to four equivalent Cr(1), two equivalent Pt(1), three equivalent Au(1), and three equivalent Au(2) atoms. Both Pt(1)-Pt(1) bond lengths are 2.76 Å. There are a spread of Pt(1)-Au(1) bond distances ranging from 2.38-3.17 Å. There are a spread of Pt(1)-Au(2) bond distances ranging from 2.38-3.17 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 2-coordinate geometry to one Cr(1) and three equivalent Pt(1) atoms. In the second Au site, Au(2) is bonded in a 1-coordinate geometry to one Cr(1) and three equivalent Pt(1) atoms.
