SrPt6P2 crystallizes in the cubic Pa-3 space group. Sr(1) is bonded to twelve equivalent Pt(1) and six equivalent P(1) atoms to form distorted edge-sharing SrP6Pt12 cuboctahedra. Pt(1) is bonded in a 10-coordinate geometry to two equivalent Sr(1), six equivalent Pt(1), and two equivalent P(1) atoms. P(1) is bonded in a 6-coordinate geometry to three equivalent Sr(1) and six equivalent Pt(1) atoms.
SrPt6P2 crystallizes in the cubic Pa-3 space group. Sr(1) is bonded to twelve equivalent Pt(1) and six equivalent P(1) atoms to form distorted edge-sharing SrP6Pt12 cuboctahedra. There are six shorter (3.27 Å) and six longer (3.29 Å) Sr(1)-Pt(1) bond lengths. All Sr(1)-P(1) bond lengths are 3.50 Å. Pt(1) is bonded in a 10-coordinate geometry to two equivalent Sr(1), six equivalent Pt(1), and two equivalent P(1) atoms. There are two shorter (2.83 Å) and four longer (2.84 Å) Pt(1)-Pt(1) bond lengths. There is one shorter (2.34 Å) and one longer (2.36 Å) Pt(1)-P(1) bond length. P(1) is bonded in a 6-coordinate geometry to three equivalent Sr(1) and six equivalent Pt(1) atoms.
