Zr4NbGa3 crystallizes in the tetragonal I4/mcm space group. Zr(1) is bonded in a 6-coordinate geometry to two equivalent Nb(1), two equivalent Ga(2), and four equivalent Ga(1) atoms. Nb(1) is bonded in a 14-coordinate geometry to eight equivalent Zr(1), two equivalent Nb(1), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to eight equivalent Zr(1) and two equivalent Nb(1) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to eight equivalent Zr(1) and two equivalent Ga(2) atoms.
