Materials Data on BaPt5 by Materials Project
BaPt5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a 6-coordinate geometry to eighteen Pt+0.40- atoms. There are six shorter (3.25 Å) and twelve longer (3.56 Å) Ba–Pt bond lengths. There are two inequivalent Pt+0.40- sites. In the first Pt+0.40- site, Pt+0.40- is bonded in a 12-coordinate geometry to three equivalent Ba2+ and six equivalent Pt+0.40- atoms. All Pt–Pt bond lengths are 2.72 Å. In the second Pt+0.40- site, Pt+0.40- is bonded to four equivalent Ba2+ and eight Pt+0.40- atoms to form a mixture of edge, corner, and face-sharing PtBa4Pt8 cuboctahedra. All Pt–Pt bond lengths are 2.82 Å.
