RuZn2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Ru(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form RuN4 tetrahedra that share corners with two equivalent Ru(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 Ru(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 Ru(1) and three equivalent Zn(1) atoms to form NZn3Ru tetrahedra that share corners with five equivalent N(2)Zn2Ru2 tetrahedra and corners with seven equivalent N(1)Zn3Ru tetrahedra. In the second N site, N(2) is bonded to two equivalent Ru(1) and two equivalent Zn(1) atoms to form NZn2Ru2 tetrahedra that share corners with two equivalent N(2)Zn2Ru2 tetrahedra and corners with ten equivalent N(1)Zn3Ru tetrahedra.

Ru(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form RuN4 tetrahedra that share corners with two equivalent Ru(1)N4 tetrahedra and corners with ten equivalent Zn(1)N4 tetrahedra. Both Ru(1)-N(1) bond lengths are 1.87 Å. There is one shorter (1.92 Å) and one longer (1.93 Å) Ru(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 Ru(1)N4 tetrahedra and corners with seven equivalent Zn(1)N4 tetrahedra. The Zn(1)-N(2) bond length is 2.10 Å. There are two shorter (2.01 Å) and one longer (2.02 Å) Zn(1)-N(1) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Ru(1) and three equivalent Zn(1) atoms to form NZn3Ru tetrahedra that share corners with five equivalent N(2)Zn2Ru2 tetrahedra and corners with seven equivalent N(1)Zn3Ru tetrahedra.
