Materials Data on La3Ta(ClO2)3 by Materials Project

La3Ta(O2Cl)3 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. La is bonded in a 10-coordinate geometry to six equivalent O and four equivalent Cl atoms. There are a spread of La–O bond distances ranging from 2.45–2.70 Å. There are a spread of La–Cl bond distances ranging from 3.05–3.11 Å. Ta is bonded in a distorted pentagonal pyramidal geometry to six equivalent O atoms. All Ta–O bond lengths are 2.01 Å. O is bonded to three equivalent La and one Ta atom to form a mixture of distorted corner and edge-sharing OLa3Ta tetrahedra. Cl is bonded in a see-saw-like geometry to four equivalent La atoms.
