Materials Data on Sr(B2Pt3)2 by Materials Project
Sr(Pt3B2)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Sr2+ is bonded to twelve equivalent Pt+1.33- atoms to form edge-sharing SrPt12 cuboctahedra. All Sr–Pt bond lengths are 3.36 Å. Pt+1.33- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and four B+1.50+ atoms. There are a spread of Pt–B bond distances ranging from 2.18–2.35 Å. There are two inequivalent B+1.50+ sites. In the first B+1.50+ site, B+1.50+ is bonded in a 6-coordinate geometry to six equivalent Pt+1.33- atoms. In the second B+1.50+ site, B+1.50+ is bonded in a 6-coordinate geometry to six equivalent Pt+1.33- atoms.
