Materials Data on La2O3 by Materials Project
La2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. there are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing LaO6 octahedra. The corner-sharing octahedra tilt angles range from 56–58°. There are a spread of La–O bond distances ranging from 2.42–2.50 Å. In the second La3+ site, La3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing LaO6 octahedra. The corner-sharing octahedral tilt angles are 58°. All La–O bond lengths are 2.45 Å. O2- is bonded to four La3+ atoms to form a mixture of distorted edge and corner-sharing OLa4 tetrahedra.
