Nb5Sn2Ga crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 6-coordinate geometry to two equivalent Nb(1) and four equivalent Sn(1) atoms. In the second Nb site, Nb(2) is bonded in a 6-coordinate geometry to two equivalent Ga(1) and four equivalent Sn(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to eight equivalent Nb(2) and two equivalent Ga(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to two equivalent Nb(1) and eight equivalent Nb(2) atoms.
