Y Sn Sn Pt
YPtSn2 crystallizes in the triclinic P1 space group. Y(1) is bonded in a 5-coordinate geometry to two equivalent Pt(1), one Sn(1), and two equivalent Sn(2) atoms. There is one shorter (2.85 Å) and one longer (3.75 Å) Y(1)-Pt(1) bond length. The Y(1)-Sn(1) bond length is 2.46 Å. There is one shorter (2.46 Å) and one longer (3.58 Å) Y(1)-Sn(2) bond length. Pt(1) is bonded in a single-bond geometry to two equivalent Y(1) and one Sn(1) atom. The Pt(1)-Sn(1) bond length is 0.67 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Y(1), one Pt(1), and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 0.88 Å. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to two equivalent Y(1) and one Sn(1) atom.
