Materials Data on Ce3Ta(Cl3O2)2 by Materials Project
Ce3Ta(O2Cl3)2 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. Ce3+ is bonded in a 2-coordinate geometry to two equivalent O2- and six Cl1- atoms. Both Ce–O bond lengths are 2.38 Å. There are a spread of Ce–Cl bond distances ranging from 2.89–3.10 Å. Ta5+ is bonded to five O2- atoms to form corner-sharing TaO5 trigonal bipyramids. There is three shorter (1.91 Å) and two longer (1.98 Å) Ta–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ce3+ and one Ta5+ atom. In the second O2- site, O2- is bonded in a linear geometry to two equivalent Ta5+ atoms. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three equivalent Ce3+ atoms. In the second Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three equivalent Ce3+ atoms.
