NaSrFePt crystallizes in the trigonal R3m space group. Na(1) is bonded to four equivalent Sr(1), four equivalent Fe(1), and six equivalent Pt(1) atoms to form distorted NaSr4Fe4Pt6 tetrahedra that share corners with six equivalent Na(1)Sr4Fe4Pt6 tetrahedra, corners with twelve equivalent Sr(1)Na4Pt4 tetrahedra, faces with four equivalent Sr(1)Na4Pt4 tetrahedra, and faces with twelve equivalent Na(1)Sr4Fe4Pt6 tetrahedra. There is one shorter (3.02 Å) and three longer (3.03 Å) Na(1)-Sr(1) bond lengths. All Na(1)-Fe(1) bond lengths are 3.03 Å. There are three shorter (3.49 Å) and three longer (3.50 Å) Na(1)-Pt(1) bond lengths. Sr(1) is bonded to four equivalent Na(1) and four equivalent Pt(1) atoms to form distorted SrNa4Pt4 tetrahedra that share corners with twelve equivalent Na(1)Sr4Fe4Pt6 tetrahedra, edges with twelve equivalent Sr(1)Na4Pt4 tetrahedra, and faces with four equivalent Na(1)Sr4Fe4Pt6 tetrahedra. All Sr(1)-Pt(1) bond lengths are 3.03 Å. Fe(1) is bonded in a distorted body-centered cubic geometry to four equivalent Na(1) and four equivalent Pt(1) atoms. All Fe(1)-Pt(1) bond lengths are 3.03 Å. Pt(1) is bonded in a distorted body-centered cubic geometry to six equivalent Na(1), four equivalent Sr(1), and four equivalent Fe(1) atoms.
