Pt2AgAl crystallizes in the monoclinic Cm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Ag(1) and four equivalent Al(1) atoms. The Pt(1)-Ag(1) bond length is 0.25 Å. There are a spread of Pt(1)-Al(1) bond distances ranging from 2.56-2.97 Å. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to four equivalent Ag(1) and one Al(1) atom. There are a spread of Pt(2)-Ag(1) bond distances ranging from 2.50-2.92 Å. The Pt(2)-Al(1) bond length is 3.07 Å. Ag(1) is bonded in a single-bond geometry to one Pt(1) and four equivalent Pt(2) atoms. Al(1) is bonded in a 5-coordinate geometry to one Pt(2) and four equivalent Pt(1) atoms.
