Materials Data on BaWO2 by Materials Project
BaWO2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Ba2+ is bonded to six equivalent O2- atoms to form edge-sharing BaO6 octahedra. There are four shorter (2.71 Å) and two longer (2.81 Å) Ba–O bond lengths. W2+ is bonded in a distorted square co-planar geometry to four equivalent O2- atoms. All W–O bond lengths are 2.23 Å. O2- is bonded to three equivalent Ba2+ and two equivalent W2+ atoms to form a mixture of distorted edge and corner-sharing OBa3W2 square pyramids.
