BeZnS2 is Enargite-like structured and crystallizes in the trigonal R3m space group. Be(1) is bonded to one S(2) and three equivalent S(1) atoms to form BeS4 tetrahedra that share corners with six equivalent Be(1)S4 tetrahedra and corners with six equivalent Zn(1)S4 tetrahedra. Zn(1) is bonded to one S(1) and three equivalent S(2) atoms to form ZnS4 tetrahedra that share corners with six equivalent Be(1)S4 tetrahedra and corners with six equivalent Zn(1)S4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to three equivalent Be(1) and one Zn(1) atom to form SBe3Zn tetrahedra that share corners with six equivalent S(1)Be3Zn tetrahedra and corners with six equivalent S(2)BeZn3 tetrahedra. In the second S site, S(2) is bonded to one Be(1) and three equivalent Zn(1) atoms to form SBeZn3 tetrahedra that share corners with six equivalent S(1)Be3Zn tetrahedra and corners with six equivalent S(2)BeZn3 tetrahedra.
