Materials Data on TbH(CO2)3 by Materials Project
TbH(CO2)3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tb3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Tb–O bond distances ranging from 2.39–2.51 Å. There are two inequivalent C+2.67+ sites. In the first C+2.67+ site, C+2.67+ 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 (1.26 Å) and one longer (1.28 Å) C–O bond length. In the second C+2.67+ site, C+2.67+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.28 Å) C–O bond length. H1+ is bonded in a single-bond geometry to one C+2.67+ atom. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Tb3+ and one C+2.67+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Tb3+ and one C+2.67+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Tb3+ and one C+2.67+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Tb3+ and one C+2.67+ atom.
