Ba2RuN3 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 7-coordinate geometry to two equivalent N(1), two equivalent N(3), and three equivalent N(2) atoms. In the second Ba site, Ba(2) is bonded to two equivalent N(1), two equivalent N(2), and three equivalent N(3) atoms to form distorted BaN7 pentagonal bipyramids that share corners with four equivalent Ba(2)N7 pentagonal bipyramids,  a cornercorner with one Ru(1)N4 tetrahedra, edges with three equivalent Ba(2)N7 pentagonal bipyramids, and edges with four equivalent Ru(1)N4 tetrahedra. Ru(1) is bonded to one N(2), one N(3), and two equivalent N(1) atoms to form RuN4 tetrahedra that share  a cornercorner with one Ba(2)N7 pentagonal bipyramid, corners with two equivalent Ru(1)N4 tetrahedra, and edges with four equivalent Ba(2)N7 pentagonal bipyramids. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), and two equivalent Ru(1) atoms. In the second N site, N(2) is bonded to two equivalent Ba(2), three equivalent Ba(1), and one Ru(1) atom to form a mixture of distorted corner and edge-sharing NBa5Ru octahedra. The corner-sharing octahedral tilt angles range from 10-63°. In the third N site, N(3) is bonded to two equivalent Ba(1), three equivalent Ba(2), and one Ru(1) atom to form a mixture of distorted corner and edge-sharing NBa5Ru octahedra. The corner-sharing octahedral tilt angles range from 17-63°.
Ba2RuN3 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 7-coordinate geometry to two equivalent N(1), two equivalent N(3), and three equivalent N(2) atoms. Both Ba(1)-N(1) bond lengths are 3.16 Å. There is one shorter (2.75 Å) and one longer (2.91 Å) Ba(1)-N(3) bond length. There are two shorter (3.01 Å) and one longer (3.08 Å) Ba(1)-N(2) bond length. In the second Ba site, Ba(2) is bonded to two equivalent N(1), two equivalent N(2), and three equivalent N(3) atoms to form distorted BaN7 pentagonal bipyramids that share corners with four equivalent Ba(2)N7 pentagonal bipyramids,  a cornercorner with one Ru(1)N4 tetrahedra, edges with three equivalent Ba(2)N7 pentagonal bipyramids, and edges with four equivalent Ru(1)N4 tetrahedra. Both Ba(2)-N(1) bond lengths are 2.93 Å. There is one shorter (2.73 Å) and one longer (2.84 Å) Ba(2)-N(2) bond length. There is one shorter (2.94 Å) and two longer (3.03 Å) Ba(2)-N(3) bond lengths.
