Materials Data on TmCO4 by Materials Project
TmCO4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Tm is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Tm–O bond distances ranging from 2.17–2.85 Å. C is bonded in a trigonal planar geometry to three O atoms. There are a spread of C–O bond distances ranging from 1.27–1.32 Å. There are four inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two equivalent Tm atoms. In the second O site, O is bonded in a distorted single-bond geometry to two equivalent Tm and one C atom. In the third O site, O is bonded in a distorted single-bond geometry to three equivalent Tm and one C atom. In the fourth O site, O is bonded in a distorted single-bond geometry to two equivalent Tm and one C atom.
