Pr(MnCo2)4 crystallizes in the tetragonal I4/mmm space group. Pr(1) is bonded in a 20-coordinate geometry to eight equivalent Mn(1), four equivalent Co(1), and eight equivalent Co(2) atoms. Mn(1) is bonded in a 10-coordinate geometry to two equivalent Pr(1), two equivalent Mn(1), four equivalent Co(1), and four equivalent Co(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 14-coordinate geometry to one Pr(1), four equivalent Mn(1), four equivalent Co(2), and five equivalent Co(1) atoms. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to two equivalent Pr(1), four equivalent Mn(1), two equivalent Co(2), and four equivalent Co(1) atoms.
