Materials Data on BaSiPt by Materials Project
BaPtSi crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Ba2+ is bonded in a 5-coordinate geometry to one Pt2+ and four equivalent Si4- atoms. The Ba–Pt bond length is 3.13 Å. There are one shorter (3.37 Å) and three longer (3.55 Å) Ba–Si bond lengths. Pt2+ is bonded to one Ba2+ and three equivalent Si4- atoms to form distorted corner-sharing PtBaSi3 trigonal pyramids. All Pt–Si bond lengths are 2.41 Å. Si4- is bonded in a 3-coordinate geometry to four equivalent Ba2+ and three equivalent Pt2+ atoms.
