Sr2YVCu2O7 crystallizes in the orthorhombic Ima2 space group. Sr(1) is bonded in a 8-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(3), and three equivalent O(4) atoms. Y(1) is bonded in a body-centered cubic geometry to four equivalent O(2) and four equivalent O(3) atoms. V(1) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form corner-sharing VO4 tetrahedra. Cu(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 1-coordinate geometry to three equivalent Sr(1) and one V(1) atom. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent V(1) atoms. In the third O site, O(2) is bonded to two equivalent Sr(1), two equivalent Y(1), and two equivalent Cu(1) atoms to form a mixture of distorted face, edge, and corner-sharing OSr2Y2Cu2 octahedra. The corner-sharing octahedral tilt angles range from 1-69°. In the fourth O site, O(3) is bonded to two equivalent Sr(1), two equivalent Y(1), and two equivalent Cu(1) atoms to form a mixture of distorted face, edge, and corner-sharing OSr2Y2Cu2 octahedra. The corner-sharing octahedral tilt angles range from 1-69°.
