Materials Data on LaCO4 by Materials Project
LaCO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. La is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of La–O bond distances ranging from 2.43–2.70 Å. C is bonded in a trigonal planar geometry to three O atoms. There is one shorter (1.28 Å) and two longer (1.30 Å) C–O bond length. There are three inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to two equivalent La and one C atom. In the second O site, O is bonded in a single-bond geometry to three equivalent La and one C atom. In the third O site, O is bonded in a water-like geometry to two equivalent La atoms.
