The structure described by Sr3V3N5 crystallizes in the triclinic P-1 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to one N(3), one N(4), one N(5), and two equivalent N(2) atoms. In the second Sr site, Sr(2) is bonded in a 7-coordinate geometry to one N(2), one N(3), one N(4), two equivalent N(1), and two equivalent N(5) atoms. In the third Sr site, Sr(3) is bonded in a 5-coordinate geometry to one N(1), one N(2), one N(4), and two equivalent N(3) atoms. There are three inequivalent V sites. In the first V site, V(1) is bonded to one N(1), one N(5), and two equivalent N(3) atoms to form a mixture of edge and corner-sharing VN4 tetrahedra. In the second V site, V(2) is bonded to one N(1), one N(2), and two equivalent N(4) atoms to form a mixture of distorted edge and corner-sharing VN4 tetrahedra. In the third V site, V(3) is bonded to one N(1), one N(2), one N(4), and one N(5) atom to form a mixture of edge and corner-sharing VN4 tetrahedra. There are five inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to one Sr(3), two equivalent Sr(2), one V(1), one V(2), and one V(3) atom. In the second N site, N(2) is bonded in a 6-coordinate geometry to one Sr(2), one Sr(3), two equivalent Sr(1), one V(2), and one V(3) atom. In the third N site, N(3) is bonded to one Sr(1), one Sr(2), two equivalent Sr(3), and two equivalent V(1) atoms to form distorted edge-sharing NSr4V2 octahedra. In the fourth N site, N(4) is bonded in a 6-coordinate geometry to one Sr(1), one Sr(2), one Sr(3), one V(3), and two equivalent V(2) atoms. In the fifth N site, N(5) is bonded in a 2-coordinate geometry to one Sr(1), two equivalent Sr(2), one V(1), and one V(3) atom. is represented by the CIF file [CIF]
