The crystal structure described by Sm(MnCo2)4 crystallizes in the tetragonal I4/mmm space group. Sm(1) is bonded to eight equivalent Mn(1), four equivalent Co(1), and eight equivalent Co(2) atoms to form a mixture of distorted corner and face-sharing SmMn8Co12 cuboctahedra. Mn(1) is bonded in a 10-coordinate geometry to two equivalent Sm(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 Sm(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 Sm(1), four equivalent Mn(1), two equivalent Co(2), and four equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
