The structure described by CaSb2O4 crystallizes in the tetragonal I-4 space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(2) atoms. In the second Ca site, Ca(2) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Sb(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ca(2) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ca(1), one Ca(2), and one Sb(1) atom. is represented by the CIF card [CIF]
