The crystal structure described by Sr2YW2O7 crystallizes in the orthorhombic Ima2 space group. Sr(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two 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. W(1) is bonded to one O(4), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing WO5 trigonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to four equivalent Sr(1) atoms. In the second O site, O(2) is bonded to two equivalent Y(1) and two equivalent W(1) atoms to form a mixture of distorted corner and edge-sharing OY2W2 tetrahedra. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to two equivalent Y(1) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one W(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
