Materials Data on OsPt4 by Materials Project
Pt2Os(Pt)2 crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of six platinum black molecules and three Pt2Os sheets oriented in the (0, 0, 1) direction. In each Pt2Os sheet, Os2- is bonded to six equivalent Os2- and six equivalent Pt+0.50+ atoms to form a mixture of face, edge, and corner-sharing OsOs6Pt6 cuboctahedra. All Os–Os bond lengths are 2.80 Å. All Os–Pt bond lengths are 2.71 Å. Pt+0.50+ is bonded in a 3-coordinate geometry to three equivalent Os2- atoms.
