YPtIn2 crystallizes in the monoclinic Cm space group. Y(1) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent In(1) atoms. There is one shorter (2.16 Å) and one longer (2.82 Å) Y(1)-Pt(1) bond length. Both Y(1)-In(1) bond lengths are 2.34 Å. Pt(1) is bonded in a distorted see-saw-like geometry to two equivalent Y(1) and two equivalent In(1) atoms. Both Pt(1)-In(1) bond lengths are 1.96 Å. In(1) is bonded in a distorted linear geometry to one Y(1) and one Pt(1) atom.
