The material structure described by MgPr4Co crystallizes in the cubic F-43m space group. Mg(1) is bonded to three equivalent Mg(1), three equivalent Pr(1), three equivalent Pr(2), and three equivalent Pr(3) atoms to form a mixture of face and corner-sharing MgPr9Mg3 cuboctahedra. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 3-coordinate geometry to three equivalent Mg(1), three equivalent Pr(2), and three equivalent Co(1) atoms. In the second Pr site, Pr(2) is bonded in a 14-coordinate geometry to two equivalent Mg(1), two equivalent Pr(1), four equivalent Pr(2), four equivalent Pr(3), and two equivalent Co(1) atoms. In the third Pr site, Pr(3) is bonded in a bent 150 degrees geometry to two equivalent Mg(1), four equivalent Pr(2), and two equivalent Co(1) atoms. Co(1) is bonded in a 6-coordinate geometry to three equivalent Pr(1), three equivalent Pr(2), and three equivalent Pr(3) atoms. is represented by the CIF card [CIF]
