Materials Data on LaWO2 by Materials Project
LaWO2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. La2+ is bonded to six equivalent O2- atoms to form edge-sharing LaO6 octahedra. There are two shorter (2.48 Å) and four longer (2.53 Å) La–O bond lengths. W2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All W–O bond lengths are 2.21 Å. O2- is bonded to three equivalent La2+ and two equivalent W2+ atoms to form a mixture of distorted edge and corner-sharing OLa3W2 trigonal bipyramids.
