Materials Data on La2C3O17 by Materials Project

Abstract

La2C2O11CO2(O2)2 crystallizes in the orthorhombic Pccn space group. The structure is two-dimensional and consists of four carbon dioxide molecules; eight hydrogen peroxide molecules; and two La2C2O11 sheets oriented in the (0, 0, 1) direction. In each La2C2O11 sheet, there are two inequivalent La sites. In the first La site, La is bonded in a distorted hexagonal bipyramidal geometry to eight O atoms. There are a spread of La–O bond distances ranging from 2.37–2.64 Å. In the second La site, La is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of La–O bond distances ranging from 2.47–2.72 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 six inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to two La and one C atom. In the second O site, O is bonded in an L-shaped geometry to one La and one O atom. The O–O bond length is 1.37 Å. In the third O site, O is bonded in a distorted single-bond geometry to two La and one C atom. In the fourth O site, O is bonded in a bent 120 degrees geometry to two equivalent O atoms. In the fifth O site, O is bonded in a distorted single-bond geometry to two La and one C atom. In the sixth O site, O is bonded in a 2-coordinate geometry to one La and one O atom. The O–O bond length is 1.34 Å.
