The compound described by Ba2SrY2PtCu2O10 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 1-coordinate geometry to three equivalent O(2) and four equivalent O(1) atoms. Sr(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(3) atoms. Y(1) is bonded in a 7-coordinate geometry to one O(2), two equivalent O(1), and four equivalent O(3) atoms. Pt(1) is bonded in an octahedral geometry to two equivalent O(2) and four equivalent O(1) atoms. Cu(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ba(1), one Sr(1), one Y(1), one Pt(1), and one Cu(1) atom to form distorted OBa2SrYCuPt octahedra that share corners with three equivalent O(1)Ba2SrYCuPt octahedra, corners with four equivalent O(2)Ba3YCuPt octahedra,  an edgeedge with one O(1)Ba2SrYCuPt octahedra, faces with two equivalent O(2)Ba3YCuPt octahedra, and faces with three equivalent O(1)Ba2SrYCuPt octahedra. The corner-sharing octahedral tilt angles range from 0-72°. In the second O site, O(2) is bonded to three equivalent Ba(1), one Y(1), one Pt(1), and one Cu(1) atom to form distorted OBa3YCuPt octahedra that share corners with three equivalent O(2)Ba3YCuPt octahedra, corners with eight equivalent O(1)Ba2SrYCuPt octahedra, edges with two equivalent O(2)Ba3YCuPt octahedra, and faces with four equivalent O(1)Ba2SrYCuPt octahedra. The corner-sharing octahedral tilt angles range from 0-66°. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Sr(1), two equivalent Y(1), and one Cu(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
