VZn2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. V(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form VN4 tetrahedra that share corners with two equivalent V(1)N4 tetrahedra and corners with ten equivalent Zn(1)N4 tetrahedra. Zn(1) is bonded to one N(2) and three equivalent N(1) atoms to form ZnN4 tetrahedra that share corners with five equivalent V(1)N4 tetrahedra and corners with seven equivalent Zn(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent V(1) and two equivalent Zn(1) atoms to form NV2Zn2 tetrahedra that share corners with two equivalent N(2)V2Zn2 tetrahedra and corners with ten equivalent N(1)VZn3 tetrahedra. In the second N site, N(1) is bonded to one V(1) and three equivalent Zn(1) atoms to form NVZn3 tetrahedra that share corners with five equivalent N(2)V2Zn2 tetrahedra and corners with seven equivalent N(1)VZn3 tetrahedra.
VZn2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. V(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form VN4 tetrahedra that share corners with two equivalent V(1)N4 tetrahedra and corners with ten equivalent Zn(1)N4 tetrahedra. Both V(1)-N(1) bond lengths are 1.78 Å. Both V(1)-N(2) bond lengths are 1.87 Å. Zn(1) is bonded to one N(2) and three equivalent N(1) atoms to form ZnN4 tetrahedra that share corners with five equivalent V(1)N4 tetrahedra and corners with seven equivalent Zn(1)N4 tetrahedra. The Zn(1)-N(2) bond length is 2.07 Å. There are two shorter (2.01 Å) and one longer (2.03 Å) Zn(1)-N(1) bond length. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent V(1) and two equivalent Zn(1) atoms to form NV2Zn2 tetrahedra that share corners with two equivalent N(2)V2Zn2 tetrahedra and corners with ten equivalent N(1)VZn3 tetrahedra.
