Pt2AgAl is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Pt2AgAl clusters. Pt(1) is bonded in a 3-coordinate geometry to one Pt(1), one Ag(1), and one Al(1) atom. The Pt(1)-Pt(1) bond length is 0.18 Å. The Pt(1)-Ag(1) bond length is 0.45 Å. The Pt(1)-Al(1) bond length is 0.45 Å. Ag(1) is bonded in a single-bond geometry to two equivalent Pt(1) and one Al(1) atom. The Ag(1)-Al(1) bond length is 0.18 Å. Al(1) is bonded in a distorted single-bond geometry to two equivalent Pt(1) and one Ag(1) atom.
