In the first Zn site, Zn(1) is bonded in a 11-coordinate geometry to two equivalent Ni(2), four equivalent Zn(3), four equivalent Zn(4), and one Ga(1) atom. In the second Zn site, Zn(2) is bonded in a 13-coordinate geometry to two equivalent Ni(1), one Zn(2), four equivalent Zn(3), four equivalent Zn(4), and two equivalent Ga(2) atoms. In the third Zn site, Zn(3) is bonded in a 2-coordinate geometry to one Ni(1), one Ni(2), two equivalent Zn(1), and two equivalent Zn(2) atoms. In the fourth Zn site, Zn(4) is bonded in a 3-coordinate geometry to one Ni(1), one Ni(2), two equivalent Zn(1), two equivalent Zn(2), and one Ga(2) atom. There are two inequivalent Ga sites.
