RePtAl2 crystallizes in the monoclinic Cm space group. Re(1) is bonded in a 12-coordinate geometry to four equivalent Re(1), four equivalent Al(1), and four equivalent Al(2) atoms. All Re(1)-Re(1) bond lengths are 2.88 Å. There are a spread of Re(1)-Al(1) bond distances ranging from 2.50-2.86 Å. There are a spread of Re(1)-Al(2) bond distances ranging from 2.72-3.06 Å. Pt(1) is bonded in a 8-coordinate geometry to four equivalent Al(1) and four equivalent Al(2) atoms. There are a spread of Pt(1)-Al(1) bond distances ranging from 2.43-2.80 Å. There are a spread of Pt(1)-Al(2) bond distances ranging from 2.43-2.80 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 8-coordinate geometry to four equivalent Re(1) and four equivalent Pt(1) atoms. In the second Al site, Al(2) is bonded in a 12-coordinate geometry to four equivalent Re(1), four equivalent Pt(1), and four equivalent Al(2) atoms. All Al(2)-Al(2) bond lengths are 2.88 Å.
