RePtAl2 crystallizes in the triclinic P1 space group. Re(1) is bonded in a single-bond geometry to one Pt(1), two equivalent Al(1), and two equivalent Al(2) atoms. The Re(1)-Pt(1) bond length is 0.15 Å. There is one shorter (2.89 Å) and one longer (3.15 Å) Re(1)-Al(1) bond length. There is one shorter (2.59 Å) and one longer (2.87 Å) Re(1)-Al(2) bond length. Pt(1) is bonded in a single-bond geometry to one Re(1), two equivalent Al(1), and two equivalent Al(2) atoms. There is one shorter (2.59 Å) and one longer (2.87 Å) Pt(1)-Al(1) bond length. There is one shorter (2.89 Å) and one longer (3.15 Å) Pt(1)-Al(2) bond length. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 8-coordinate geometry to two equivalent Re(1), two equivalent Pt(1), two equivalent Al(1), and two equivalent Al(2) atoms. Both Al(1)-Al(1) bond lengths are 2.80 Å. There is one shorter (2.26 Å) and one longer (2.32 Å) Al(1)-Al(2) bond length. In the second Al site, Al(2) is bonded in a 8-coordinate geometry to two equivalent Re(1), two equivalent Pt(1), two equivalent Al(1), and two equivalent Al(2) atoms. Both Al(2)-Al(2) bond lengths are 2.80 Å.
