The material structure described by Ca2YSbO5 crystallizes in the monoclinic Cc space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(5) atoms. In the second Ca site, Ca(2) is bonded to one O(1), one O(4), and two equivalent O(3) atoms to form distorted CaO4 trigonal pyramids that share corners with four equivalent Y(1)O4 tetrahedra and corners with two equivalent Ca(2)O4 trigonal pyramids. Y(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form YO4 tetrahedra that share corners with two equivalent Y(1)O4 tetrahedra and corners with four equivalent Ca(2)O4 trigonal pyramids. Sb(1) is bonded in a 3-coordinate geometry to one O(2), one O(4), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded to one Ca(1), one Ca(2), and two equivalent Y(1) atoms to form corner-sharing OCa2Y2 tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ca(1), one Y(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to two equivalent Ca(2) and one Y(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Ca(1), one Ca(2), and one Sb(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Ca(1) and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
