Sr2VN3 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 6-coordinate geometry to one N(2), two equivalent N(1), and three equivalent N(4) atoms. In the second Sr site, Sr(2) is bonded to one N(2), one N(3), two equivalent N(4), and three equivalent N(1) atoms to form distorted SrN7 pentagonal bipyramids that share corners with four equivalent Sr(2)N7 pentagonal bipyramids,  a cornercorner with one V(1)N4 tetrahedra, edges with three equivalent Sr(2)N7 pentagonal bipyramids, and edges with four equivalent V(1)N4 tetrahedra. V(1) is bonded to one N(1), one N(2), one N(3), and one N(4) atom to form VN4 tetrahedra that share  a cornercorner with one Sr(2)N7 pentagonal bipyramid, corners with two equivalent V(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(1) is bonded in a 6-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), and one V(1) atom. In the second N site, N(2) is bonded in a 2-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent V(1) atoms. In the third N site, N(3) is bonded in a 4-coordinate geometry to two equivalent Sr(2) and two equivalent V(1) atoms. In the fourth N site, N(4) is bonded in a 6-coordinate geometry to two equivalent Sr(2), three equivalent Sr(1), and one V(1) atom.
