Materials Data on BaH6C4O7 by Materials Project
BaH6(CO2)3CO crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two formaldehyde molecules and one BaH6(CO2)3 ribbon oriented in the (1, 0, 1) direction. In the BaH6(CO2)3 ribbon, Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–2.91 Å. There are three inequivalent C+1.50+ sites. In the first C+1.50+ site, C+1.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.26 Å. In the second C+1.50+ site, C+1.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.26 Å. In the third C+1.50+ site, C+1.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.26 Å. There are six 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 O2- atom. The H–O bond length is 0.99 Å. 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 1.00 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+ and one C+1.50+ atom. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Ba2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a water-like geometry to one Ba2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a water-like geometry to one Ba2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one C+1.50+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one C+1.50+ atom.
