The crystal structure described by MgFeAgS2 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 6-coordinate geometry to three equivalent Ag(1) and three equivalent S(1) atoms. Fe(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form edge-sharing FeS6 octahedra. Ag(1) is bonded in a 6-coordinate geometry to three equivalent Mg(1) and three equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to three equivalent Mg(1) and three equivalent Fe(1) atoms to form distorted edge-sharing SMg3Fe3 pentagonal pyramids. In the second S site, S(2) is bonded in a 6-coordinate geometry to three equivalent Fe(1) and three equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
