NaSn3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Na(1) is bonded to four equivalent Sn(2) and eight equivalent Sn(1) atoms to form a mixture of edge, corner, and face-sharing NaSn12 cuboctahedra. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to four equivalent Na(1) atoms to form a mixture of distorted edge and corner-sharing SnNa4 cuboctahedra. In the second Sn site, Sn(2) is bonded in a square co-planar geometry to four equivalent Na(1) atoms.
