The compound described by OsZn2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Os(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form OsN4 tetrahedra that share corners with two equivalent Os(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 Os(1)N4 tetrahedra and corners with seven equivalent Zn(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Os(1) and three equivalent Zn(1) atoms to form NZn3Os tetrahedra that share corners with five equivalent N(2)Zn2Os2 tetrahedra and corners with seven equivalent N(1)Zn3Os tetrahedra. In the second N site, N(2) is bonded to two equivalent Os(1) and two equivalent Zn(1) atoms to form NZn2Os2 tetrahedra that share corners with two equivalent N(2)Zn2Os2 tetrahedra and corners with ten equivalent N(1)Zn3Os tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
