The structure described by Mg3Pr4Co2 crystallizes in the monoclinic P2/m space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to one Mg(1), four equivalent Pr(1), four equivalent Pr(2), and one Co(1) atom. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to four equivalent Pr(1), four equivalent Pr(2), and two equivalent Co(1) atoms. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a distorted L-shaped geometry to two equivalent Mg(2), four equivalent Mg(1), and two equivalent Co(1) atoms. In the second Pr site, Pr(2) is bonded in a 4-coordinate geometry to two equivalent Mg(2), four equivalent Mg(1), and four equivalent Co(1) atoms. Co(1) is bonded in a 9-coordinate geometry to one Mg(1), one Mg(2), two equivalent Pr(1), four equivalent Pr(2), and one Co(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
