The crystal structure described by K3MgSbS4 crystallizes in the trigonal R3m space group. K(1) is bonded in a 8-coordinate geometry to one Mg(1), one Sb(1), two equivalent S(1), and four equivalent S(2) atoms. Mg(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent K(1), one S(1), and three equivalent S(2) atoms. Sb(1) is bonded in a 3-coordinate geometry to three equivalent K(1) and three equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 7-coordinate geometry to six equivalent K(1) and one Mg(1) atom. In the second S site, S(2) is bonded in a 6-coordinate geometry to four equivalent K(1), one Mg(1), and one Sb(1) atom. is represented by the CIF file [CIF]
