WZn3N4 is Enargite structured and crystallizes in the orthorhombic Pmn2_1 space group. W(1) is bonded to one N(2), one N(3), and two equivalent N(1) atoms to form WN4 tetrahedra that share corners with four equivalent Zn(2)N4 tetrahedra and corners with eight equivalent Zn(1)N4 tetrahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one N(2), one N(3), and two equivalent N(1) atoms to form ZnN4 tetrahedra that share corners with four equivalent W(1)N4 tetrahedra, corners with four equivalent Zn(1)N4 tetrahedra, and corners with four equivalent Zn(2)N4 tetrahedra. In the second Zn site, Zn(2) is bonded to one N(2), one N(3), and two equivalent N(1) atoms to form ZnN4 tetrahedra that share corners with four equivalent W(1)N4 tetrahedra and corners with eight equivalent Zn(1)N4 tetrahedra. There are three inequivalent N sites. In the first N site, N(1) is bonded to one W(1), one Zn(2), and two equivalent Zn(1) atoms to form corner-sharing NZn3W tetrahedra. In the second N site, N(2) is bonded to one W(1), one Zn(2), and two equivalent Zn(1) atoms to form corner-sharing NZn3W tetrahedra. In the third N site, N(3) is bonded to one W(1), one Zn(2), and two equivalent Zn(1) atoms to form corner-sharing NZn3W tetrahedra.
