Materials Data on CuPt3 by Materials Project
PtPt2Cu crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two platinum molecules and one Pt2Cu sheet oriented in the (0, 0, 1) direction. In the Pt2Cu sheet, Pt+0.67- is bonded in a 2-coordinate geometry to two equivalent Pt+0.67- and two equivalent Cu2+ atoms. Both Pt–Pt bond lengths are 2.42 Å. Both Pt–Cu bond lengths are 2.47 Å. Cu2+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent Pt+0.67- atoms.
