VPtAl2 crystallizes in the triclinic P1 space group. V(1) is bonded in a 3-coordinate geometry to one Pt(1), one Al(1), and one Al(2) atom. The V(1)-Pt(1) bond length is 2.45 Å. The V(1)-Al(1) bond length is 1.51 Å. The V(1)-Al(2) bond length is 1.75 Å. Pt(1) is bonded in a 5-coordinate geometry to one V(1), two equivalent Al(1), and two equivalent Al(2) atoms. There is one shorter (1.90 Å) and one longer (2.10 Å) Pt(1)-Al(1) bond length. There is one shorter (2.66 Å) and one longer (2.78 Å) Pt(1)-Al(2) bond length. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted T-shaped geometry to one V(1) and two equivalent Pt(1) atoms. In the second Al site, Al(2) is bonded in a 3-coordinate geometry to one V(1) and two equivalent Pt(1) atoms.
