NaSrPt crystallizes in the triclinic P1 space group. Na(1) is bonded in a 3-coordinate geometry to four equivalent Sr(1) and two equivalent Pt(1) atoms. There are a spread of Na(1)-Sr(1) bond distances ranging from 2.08-3.83 Å. There is one shorter (3.01 Å) and one longer (3.69 Å) Na(1)-Pt(1) bond length. Sr(1) is bonded in a 6-coordinate geometry to four equivalent Na(1) and two equivalent Pt(1) atoms. There is one shorter (3.60 Å) and one longer (3.67 Å) Sr(1)-Pt(1) bond length. Pt(1) is bonded in a 4-coordinate geometry to two equivalent Na(1) and two equivalent Sr(1) atoms.
