MgPrTl crystallizes in the hexagonal P-62m space group. Mg(1) is bonded in a 4-coordinate geometry to two equivalent Tl(1) and two equivalent Tl(2) atoms. Pr(1) is bonded in a 5-coordinate geometry to one Tl(2) and four equivalent Tl(1) atoms. There are two inequivalent Tl sites. In the first Tl site, Tl(2) is bonded in a distorted q6 geometry to six equivalent Mg(1) and three equivalent Pr(1) atoms. In the second Tl site, Tl(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Pr(1) atoms.
