YbZnGa3 crystallizes in the tetragonal I4mm space group. Yb(1) is bonded in a 16-coordinate geometry to four equivalent Zn(1), four equivalent Ga(1), and eight equivalent Ga(2) atoms. Zn(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), one Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), one Zn(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 12-coordinate geometry to four equivalent Yb(1), two equivalent Zn(1), two equivalent Ga(1), and four equivalent Ga(2) atoms.
