Materials Data on TmH3(CO2)3 by Materials Project

TmH3(CO2)3 crystallizes in the trigonal R3m space group. The structure is three-dimensional. Tm3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Tm–O bond distances ranging from 2.35–2.49 Å. C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.10 Å. There is one shorter (1.27 Å) and one longer (1.28 Å) C–O bond length. H1+ is bonded in a single-bond geometry to one C2+ atom. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Tm3+ and one C2+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Tm3+ and one C2+ atom.
