Materials Data on YbH7C3O8 by Materials Project
YbC3H7O8 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two YbC3H7O8 ribbons oriented in the (1, 0, 0) direction. Yb3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Yb–O bond distances ranging from 2.33–2.51 Å. There are three inequivalent C2+ sites. In the first C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.12 Å. Both C–O bond lengths are 1.27 Å. In the second C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.13 Å. Both C–O bond lengths are 1.25 Å. In the third C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å. Both C–O bond lengths are 1.27 Å. There are seven inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Yb3+ and one C2+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Yb3+ and one C2+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Yb3+ and one C2+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Yb3+ and one C2+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Yb3+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to one Yb3+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one Yb3+ and one C2+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to one Yb3+ and one C2+ atom.
