The material structure described by Mg3Co2Ga7 crystallizes in the monoclinic C2/c space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 9-coordinate geometry to two equivalent Co(1), two equivalent Ga(4), three equivalent Ga(2), and three equivalent Ga(3) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Co(1), two equivalent Ga(2), two equivalent Ga(3), and four equivalent Ga(4) atoms. Co(1) is bonded in a 9-coordinate geometry to one Mg(2), two equivalent Mg(1), one Ga(1), one Ga(3), two equivalent Ga(2), and two equivalent Ga(4) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 2-coordinate geometry to two equivalent Co(1), two equivalent Ga(2), two equivalent Ga(3), and two equivalent Ga(4) atoms. In the second Ga site, Ga(2) is bonded in a 11-coordinate geometry to one Mg(2), three equivalent Mg(1), two equivalent Co(1), one Ga(1), one Ga(2), one Ga(3), and two equivalent Ga(4) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to one Mg(2), three equivalent Mg(1), one Co(1), one Ga(1), one Ga(2), one Ga(3), and one Ga(4) atom. In the fourth Ga site, Ga(4) is bonded in a 11-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), two equivalent Co(1), one Ga(1), one Ga(3), one Ga(4), and two equivalent Ga(2) atoms. is represented by the CIF card [CIF]
