The crystal structure described by MgZn2(CoS2)4 crystallizes in the monoclinic Cm space group. Mg(1) is bonded to one S(5), one S(6), two equivalent S(2), and two equivalent S(4) atoms to form MgS6 octahedra that share corners with eight equivalent Co(1)S6 octahedra, corners with three equivalent Co(2)S4 trigonal pyramids, and corners with three equivalent Co(3)S4 trigonal pyramids.
