The crystal structure described by CaWO2 crystallizes in the tetragonal I4_1/amd space group. Ca(1) is bonded to six equivalent O(1) atoms to form edge-sharing CaO6 octahedra. W(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Ca(1) and two equivalent W(1) atoms to form a mixture of distorted corner and edge-sharing OCa3W2 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
