Y Pt Au Au
YPtAu2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YPtAu2 clusters. Y(1) is bonded in a bent 150 degrees geometry to one Au(1) and one Au(2) atom. The Y(1)-Au(1) bond length is 1.42 Å. The Y(1)-Au(2) bond length is 0.82 Å. Pt(1) is bonded in a distorted single-bond geometry to one Au(1) atom. The Pt(1)-Au(1) bond length is 1.08 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted bent 150 degrees geometry to one Y(1) and one Pt(1) atom. In the second Au site, Au(2) is bonded in a single-bond geometry to one Y(1) atom.
