Ba3Sn2 crystallizes in the tetragonal P4_32_12 space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to three equivalent Ba(2), six equivalent Ba(1), and one Sn(1) atom.
