Materials Data on LaCO4 by Materials Project

Abstract

LaCO4 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are three inequivalent La sites. In the first La site, La is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of La–O bond distances ranging from 2.48–2.77 Å. In the second La site, La is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of La–O bond distances ranging from 2.49–2.75 Å. In the third La site, La is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of La–O bond distances ranging from 2.47–2.65 Å. There are six inequivalent C sites. In the first C site, C is bonded in a trigonal planar geometry to three O atoms. All C–O bond lengths are 1.30 Å. In the second C site, C is bonded in a trigonal planar geometry to three O atoms. All C–O bond lengths are 1.30 Å. In the third C site, C is bonded in a trigonal planar geometry to three O atoms. There is two shorter (1.29 Å) and one longer (1.30 Å) C–O bond length. In the fourth C site, C is bonded in a trigonal planar geometry to three O atoms. All C–O bond lengths are 1.30 Å. In the fifth C site, C is bonded in a trigonal planar geometry to three O atoms. All C–O bond lengths are 1.30 Å. In the sixth C site, C is bonded in a trigonal planar geometry to three O atoms. There is two shorter (1.29 Å) and one longer (1.30 Å) C–O bond length. There are seventeen 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 distorted single-bond geometry to two 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 distorted single-bond geometry to two La and one C atom. In the fifth O site, O is bonded in a single-bond geometry to two equivalent La and one C atom. In the sixth O site, O is bonded in a distorted single-bond geometry to two La and one C atom. In the seventh O site, O is bonded in a distorted single-bond geometry to two equivalent La and one C atom. In the eighth O site, O is bonded in a distorted single-bond geometry to two La and one C atom. In the ninth O site, O is bonded in a distorted single-bond geometry to two equivalent La and one C atom. In the tenth O site, O is bonded in a distorted single-bond geometry to two La and one C atom. In the eleventh O site, O is bonded in a single-bond geometry to two equivalent La and one C atom. In the twelfth O site, O is bonded in a distorted single-bond geometry to two La and one C atom. In the thirteenth O site, O is bonded in a trigonal planar geometry to three equivalent La atoms. In the fourteenth O site, O is bonded in a trigonal planar geometry to three equivalent La atoms. In the fifteenth O site, O is bonded in a trigonal planar geometry to three equivalent La atoms. In the sixteenth O site, O is bonded in a trigonal non-coplanar geometry to three La atoms. In the seventeenth O site, O is bonded in a trigonal non-coplanar geometry to three La atoms.
