Al Al Pt W
WPtAl2 crystallizes in the triclinic P1 space group. W(1) is bonded in a 9-coordinate geometry to two equivalent W(1), two equivalent Pt(1), two equivalent Al(2), and three equivalent Al(1) atoms. Both W(1)-W(1) bond lengths are 2.91 Å. There is one shorter (2.23 Å) and one longer (2.41 Å) W(1)-Pt(1) bond length. There is one shorter (2.32 Å) and one longer (3.13 Å) W(1)-Al(2) bond length. There are a spread of W(1)-Al(1) bond distances ranging from 2.53-3.05 Å. Pt(1) is bonded in a 2-coordinate geometry to two equivalent W(1) and one Al(2) atom. The Pt(1)-Al(2) bond length is 1.98 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to three equivalent W(1) and one Al(2) atom. The Al(1)-Al(2) bond length is 0.61 Å. In the second Al site, Al(2) is bonded in a 3-coordinate geometry to two equivalent W(1), one Pt(1), and one Al(1) atom.
