The material described by Sr2RuN3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 7-coordinate geometry to one N(1), one N(4), two equivalent N(3), and three equivalent N(2) atoms. In the second Sr site, Sr(2) is bonded to one N(1), one N(4), two equivalent N(2), and three equivalent N(3) atoms to form distorted SrN7 pentagonal bipyramids that share corners with four equivalent Sr(2)N7 pentagonal bipyramids,  a cornercorner with one Ru(1)N4 tetrahedra, edges with three equivalent Sr(2)N7 pentagonal bipyramids, and edges with four equivalent Ru(1)N4 tetrahedra. Ru(1) is bonded to one N(1), one N(2), one N(3), and one N(4) atom to form RuN4 tetrahedra that share  a cornercorner with one Sr(2)N7 pentagonal bipyramid, corners with two equivalent Ru(1)N4 tetrahedra, and edges with four equivalent Sr(2)N7 pentagonal bipyramids. There are four inequivalent N sites. In the first N site, N(4) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Ru(1) atoms to form distorted NSr4Ru2 octahedra that share corners with four equivalent N(3)Sr5Ru octahedra, corners with six equivalent N(2)Sr5Ru octahedra, edges with three equivalent N(1)Sr4Ru2 octahedra, edges with four equivalent N(3)Sr5Ru octahedra, and faces with two equivalent N(2)Sr5Ru octahedra. The corner-sharing octahedral tilt angles range from 22-79°. In the second N site, N(1) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Ru(1) atoms to form distorted NSr4Ru2 octahedra that share corners with six equivalent N(2)Sr5Ru octahedra, corners with six equivalent N(3)Sr5Ru octahedra, edges with three equivalent N(4)Sr4Ru2 octahedra, faces with two equivalent N(2)Sr5Ru octahedra, and faces with two equivalent N(3)Sr5Ru octahedra. The corner-sharing octahedral tilt angles range from 39-63°. In the third N site, N(2) is bonded to two equivalent Sr(2), three equivalent Sr(1), and one Ru(1) atom to form distorted NSr5Ru octahedra that share corners with two equivalent N(2)Sr5Ru octahedra, corners with three equivalent N(1)Sr4Ru2 octahedra, corners with three equivalent N(4)Sr4Ru2 octahedra, corners with three equivalent N(3)Sr5Ru octahedra, edges with three equivalent N(2)Sr5Ru octahedra, edges with five equivalent N(3)Sr5Ru octahedra,  a faceface with one N(1)Sr4Ru2 octahedra, and  a faceface with one N(4)Sr4Ru2 octahedra. The corner-sharing octahedral tilt angles range from 18-79°. In the fourth N site, N(3) is bonded to two equivalent Sr(1), three equivalent Sr(2), and one Ru(1) atom to form distorted NSr5Ru octahedra that share corners with two equivalent N(4)Sr4Ru2 octahedra, corners with two equivalent N(3)Sr5Ru octahedra, corners with three equivalent N(1)Sr4Ru2 octahedra, corners with three equivalent N(2)Sr5Ru octahedra, edges with two equivalent N(4)Sr4Ru2 octahedra, edges with three equivalent N(3)Sr5Ru octahedra, edges with five equivalent N(2)Sr5Ru octahedra, and  a faceface with one N(1)Sr4Ru2 octahedra.
