Materials Data on NaSn3 by Materials Project
NaSn3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Na is bonded to twelve equivalent Sn atoms to form a mixture of face and corner-sharing NaSn12 cuboctahedra. There are six shorter (3.36 Å) and six longer (3.47 Å) Na–Sn bond lengths. Sn is bonded in a 4-coordinate geometry to four equivalent Na atoms.
