Materials Data on ErCO4 by Materials Project

ErCO4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Er is bonded in a 8-coordinate geometry to nine O atoms. There are a spread of Er–O bond distances ranging from 2.19–2.86 Å. C is bonded in a trigonal planar geometry to three O atoms. There are a spread of C–O bond distances ranging from 1.28–1.31 Å. There are four inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two equivalent Er atoms. In the second O site, O is bonded in a distorted single-bond geometry to two equivalent Er and one C atom. In the third O site, O is bonded in a distorted single-bond geometry to three equivalent Er and one C atom. In the fourth O site, O is bonded in a distorted single-bond geometry to two equivalent Er and one C atom.

Materials Data on ErC3O8 by Materials Project

ErC3O8 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Er is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Er–O bond distances ranging from 2.09–2.69 Å. There are three inequivalent C sites. In the first C site, C is bonded in a linear geometry to two O atoms. There is one shorter (1.17 Å) and one longer (1.18 Å) C–O bond length. In the second C site, C is bonded in a linear geometry to two O atoms. There is one shorter (1.17 Å) and one longer (1.18 Å) C–O bond length. In the third C site, C is bonded in a trigonal planar geometry to three O atoms. There are a spread of C–O bond distances ranging from 1.28–1.31 Å. There are eight inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to one Er and one C atom. In the second O site, O is bonded in an L-shaped geometry to one Er and one C atom. In the third O site, O is bonded in a single-bond geometry to one Er atom. In the fourth O site, O is bonded in an L-shaped geometry to one Er and one C atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one Er and one C atom. In the sixth O site, O is bonded in a distorted linear geometry to one Er and one C atom. In the seventh O site, O is bonded in a single-bond geometry to one C atom. In the eighth O site, O is bonded in a distorted linear geometry to one Er and one C atom.
