The structure described by CaSbAsO5 crystallizes in the orthorhombic P2_12_12_1 space group. Ca(1) is bonded in a 6-coordinate geometry to one O(3), one O(4), two equivalent O(2), and two equivalent O(5) atoms. Sb(1) is bonded to one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form distorted SbO5 square pyramids that share corners with two equivalent Sb(1)O5 square pyramids and corners with four equivalent As(1)O4 tetrahedra. As(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form AsO4 tetrahedra that share corners with four equivalent Sb(1)O5 square pyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Sb(1) and one As(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ca(1) and one As(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ca(1), one Sb(1), and one As(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Ca(1), one Sb(1), and one As(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ca(1) and one Sb(1) atom. is represented by the CIF card [CIF]
