The material structure described by CaSb2O4 crystallizes in the orthorhombic Pbcm space group. Ca(1) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(1) atoms. Sb(1) is bonded in a distorted see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ca(1) and two equivalent Sb(1) atoms to form a mixture of distorted edge and corner-sharing OCa2Sb2 tetrahedra. In the second O site, O(2) is bonded in a water-like geometry to two equivalent Sb(1) atoms. In the third O site, O(3) is bonded to two equivalent Ca(1) and two equivalent Sb(1) atoms to form a mixture of edge and corner-sharing OCa2Sb2 trigonal pyramids. is represented by the CIF file [CIF]
