OsPt2Cu is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsPt2Cu clusters. Os(1) is bonded in a 2-coordinate geometry to two equivalent Pt(1) atoms. Both Os(1)-Pt(1) bond lengths are 0.61 Å. Pt(1) is bonded in a single-bond geometry to one Os(1) and one Cu(1) atom. The Pt(1)-Cu(1) bond length is 0.27 Å. Cu(1) is bonded in an L-shaped geometry to two equivalent Pt(1) atoms.
