SrPtSi crystallizes in the cubic P2_13 space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Pt(1) and four equivalent Si(1) atoms. Pt(1) is bonded in a 7-coordinate geometry to four equivalent Sr(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 3-coordinate geometry to four equivalent Sr(1) and three equivalent Pt(1) atoms.
SrPtSi crystallizes in the cubic P2_13 space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Pt(1) and four equivalent Si(1) atoms. There is one shorter (3.16 Å) and three longer (3.31 Å) Sr(1)-Pt(1) bond lengths. There is one shorter (3.28 Å) and three longer (3.37 Å) Sr(1)-Si(1) bond lengths. Pt(1) is bonded in a 7-coordinate geometry to four equivalent Sr(1) and three equivalent Si(1) atoms. All Pt(1)-Si(1) bond lengths are 2.35 Å. Si(1) is bonded in a 3-coordinate geometry to four equivalent Sr(1) and three equivalent Pt(1) atoms.
