Materials Data on Pt2W by Materials Project
Pt2W crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. W4+ is bonded in a distorted q6 geometry to ten equivalent Pt2- atoms. There are eight shorter (2.79 Å) and two longer (2.82 Å) W–Pt bond lengths. Pt2- is bonded to five equivalent W4+ and seven equivalent Pt2- atoms to form a mixture of edge, face, and corner-sharing PtPt7W5 cuboctahedra. There are a spread of Pt–Pt bond distances ranging from 2.73–2.83 Å.
