NaSr3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded to twelve equivalent Sr(1) atoms to form NaSr12 cuboctahedra that share corners with six equivalent Na(1)Sr12 cuboctahedra, corners with twelve equivalent Sr(1)Na4Sr8 cuboctahedra, edges with eighteen equivalent Sr(1)Na4Sr8 cuboctahedra, faces with eight equivalent Na(1)Sr12 cuboctahedra, and faces with twelve equivalent Sr(1)Na4Sr8 cuboctahedra. Sr(1) is bonded to four equivalent Na(1) and eight equivalent Sr(1) atoms to form SrNa4Sr8 cuboctahedra that share corners with four equivalent Na(1)Sr12 cuboctahedra, corners with fourteen equivalent Sr(1)Na4Sr8 cuboctahedra, edges with six equivalent Na(1)Sr12 cuboctahedra, edges with twelve equivalent Sr(1)Na4Sr8 cuboctahedra, faces with four equivalent Na(1)Sr12 cuboctahedra, and faces with sixteen equivalent Sr(1)Na4Sr8 cuboctahedra.

There are six shorter (4.20 Å) and six longer (4.22 Å) Na(1)-Sr(1) bond lengths. Sr(1) is bonded to four equivalent Na(1) and eight equivalent Sr(1) atoms to form SrNa4Sr8 cuboctahedra that share corners with four equivalent Na(1)Sr12 cuboctahedra, corners with fourteen equivalent Sr(1)Na4Sr8 cuboctahedra, edges with six equivalent Na(1)Sr12 cuboctahedra, edges with twelve equivalent Sr(1)Na4Sr8 cuboctahedra, faces with four equivalent Na(1)Sr12 cuboctahedra, and faces with sixteen equivalent Sr(1)Na4Sr8 cuboctahedra. There are two shorter (4.17 Å) and six longer (4.23 Å) Sr(1)-Sr(1) bond lengths.
