Sr3(VN2)2 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form edge-sharing VN4 tetrahedra. In the second V site, V(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing VN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 7-coordinate geometry to two equivalent Sr(2), three equivalent Sr(1), one V(1), and one V(2) atom. In the second N site, N(2) is bonded in a 6-coordinate geometry to one Sr(2), three equivalent Sr(1), one V(1), and one V(2) atom.
