The material structure described by Mg2TeS is Enargite-like structured and crystallizes in the trigonal R3m space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to one Te(1) and three equivalent S(1) atoms to form MgTeS3 tetrahedra that share corners with six equivalent Mg(2)Te3S tetrahedra and corners with six equivalent Mg(1)TeS3 tetrahedra. In the second Mg site, Mg(2) is bonded to three equivalent Te(1) and one S(1) atom to form MgTe3S tetrahedra that share corners with six equivalent Mg(2)Te3S tetrahedra and corners with six equivalent Mg(1)TeS3 tetrahedra. Te(1) is bonded to one Mg(1) and three equivalent Mg(2) atoms to form TeMg4 tetrahedra that share corners with six equivalent Te(1)Mg4 tetrahedra and corners with six equivalent S(1)Mg4 tetrahedra. S(1) is bonded to one Mg(2) and three equivalent Mg(1) atoms to form SMg4 tetrahedra that share corners with six equivalent Te(1)Mg4 tetrahedra and corners with six equivalent S(1)Mg4 tetrahedra. is represented by the CIF file [CIF]
