Materials Data on SrSiPt by Materials Project

SrPtSi crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Sr2+ is bonded in a 4-coordinate geometry to four equivalent Si4- atoms. There are one shorter (3.31 Å) and three longer (3.38 Å) Sr–Si bond lengths. Pt2+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Pt–Si bond lengths are 2.37 Å. Si4- is bonded in a 3-coordinate geometry to four equivalent Sr2+ and three equivalent Pt2+ atoms.
