Materials Data on LaCO4 by Materials Project

Abstract

LaCO4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. La is bonded in a 2-coordinate geometry to ten O atoms. There are a spread of La–O bond distances ranging from 2.37–3.05 Å. C is bonded in a trigonal planar geometry to three O atoms. There are a spread of C–O bond distances ranging from 1.29–1.31 Å. There are four inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two equivalent La atoms. In the second O site, O is bonded in a distorted single-bond geometry to three equivalent La and one C atom. In the third O site, O is bonded in a distorted single-bond geometry to two equivalent La and one C atom. In the fourth O site, O is bonded in a single-bond geometry to three equivalent La and one C atom.
