ReZn2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Re(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form ReN4 tetrahedra that share corners with two equivalent Re(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 Re(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 Re(1) and three equivalent Zn(1) atoms to form NZn3Re tetrahedra that share corners with five equivalent N(2)Zn2Re2 tetrahedra and corners with seven equivalent N(1)Zn3Re tetrahedra. In the second N site, N(2) is bonded to two equivalent Re(1) and two equivalent Zn(1) atoms to form NZn2Re2 tetrahedra that share corners with two equivalent N(2)Zn2Re2 tetrahedra and corners with ten equivalent N(1)Zn3Re tetrahedra.

Re(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form ReN4 tetrahedra that share corners with two equivalent Re(1)N4 tetrahedra and corners with ten equivalent Zn(1)N4 tetrahedra. Both Re(1)-N(1) bond lengths are 1.88 Å. There is one shorter (1.96 Å) and one longer (2.01 Å) Re(1)-N(2) bond length. Zn(1) is bonded to one N(2) and three equivalent N(1) atoms to form ZnN4 tetrahedra that share corners with five equivalent Re(1)N4 tetrahedra and corners with seven equivalent Zn(1)N4 tetrahedra. The Zn(1)-N(2) bond length is 2.09 Å. There are a spread of Zn(1)-N(1) bond distances ranging from 2.04-2.07 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Re(1) and three equivalent Zn(1) atoms to form NZn3Re tetrahedra that share corners with five equivalent N(2)Zn2Re2 tetrahedra and corners with seven equivalent N(1)Zn3Re tetrahedra.
