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.
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. There are two shorter (2.36 Å) and four longer (2.41 Å) Ca(1)-O(1) bond lengths. W(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All W(1)-O(1) bond lengths are 2.19 Å. 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.
