The compound described by SrV2CuO7 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 11-coordinate geometry to one O(5), two equivalent O(2), four equivalent O(3), and four equivalent O(4) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form VO4 tetrahedra that share corners with three equivalent Cu(1)O5 square pyramids and  a cornercorner with one V(2)O4 tetrahedra. In the second V site, V(2) is bonded to one O(2), one O(5), and two equivalent O(4) atoms to form VO4 tetrahedra that share corners with two equivalent Cu(1)O5 square pyramids and  a cornercorner with one V(1)O4 tetrahedra. Cu(1) is bonded to one O(1), two equivalent O(3), and two equivalent O(4) atoms to form CuO5 square pyramids that share corners with two equivalent V(2)O4 tetrahedra and corners with three equivalent V(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 150 degrees geometry to two equivalent Sr(1), one V(2), and one Cu(1) atom. In the second O site, O(5) is bonded in a distorted linear geometry to one Sr(1) and one V(2) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one V(1) and one Cu(1) atom. In the fourth O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Sr(1), one V(1), and one V(2) atom. In the fifth O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one V(1), and one Cu(1) atom. is represented by the CIF card [CIF]
