Zn2SbN3 is Chalcopyrite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Zn(1) is bonded to one N(2) and three equivalent N(1) atoms to form ZnN4 tetrahedra that share corners with five equivalent Sb(1)N4 tetrahedra and corners with seven equivalent Zn(1)N4 tetrahedra. Sb(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form SbN4 tetrahedra that share corners with two equivalent Sb(1)N4 tetrahedra and corners with ten equivalent Zn(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Zn(1) and one Sb(1) atom to form NZn3Sb tetrahedra that share corners with five equivalent N(2)Zn2Sb2 tetrahedra and corners with seven equivalent N(1)Zn3Sb tetrahedra. In the second N site, N(2) is bonded to two equivalent Zn(1) and two equivalent Sb(1) atoms to form NZn2Sb2 tetrahedra that share corners with two equivalent N(2)Zn2Sb2 tetrahedra and corners with ten equivalent N(1)Zn3Sb 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 Sb(1)N4 tetrahedra and corners with seven equivalent Zn(1)N4 tetrahedra. The Zn(1)-N(2) bond length is 2.13 Å. There are two shorter (2.02 Å) and one longer (2.03 Å) Zn(1)-N(1) bond length. Sb(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form SbN4 tetrahedra that share corners with two equivalent Sb(1)N4 tetrahedra and corners with ten equivalent Zn(1)N4 tetrahedra. Both Sb(1)-N(1) bond lengths are 1.97 Å. There is one shorter (2.04 Å) and one longer (2.05 Å) Sb(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Zn(1) and one Sb(1) atom to form NZn3Sb tetrahedra that share corners with five equivalent N(2)Zn2Sb2 tetrahedra and corners with seven equivalent N(1)Zn3Sb tetrahedra.
