Cu Pt Pt W
CuW(Pt)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CuW cluster and one Pt cluster. In the CuW cluster, W(1) is bonded in a single-bond geometry to one Cu(1) atom. The W(1)-Cu(1) bond length is 1.04 Å. Cu(1) is bonded in a distorted single-bond geometry to one W(1) atom. In the Pt cluster, there are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Pt(2) atom. The Pt(1)-Pt(2) bond length is 0.46 Å. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Pt(1) atom.
