Materials Data on BaH2Cl2O by Materials Project
BaH2OCl2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to two equivalent O2- and seven Cl1- atoms. Both Ba–O bond lengths are 2.87 Å. There are a spread of Ba–Cl bond distances ranging from 3.18–3.50 Å. There are two 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 0.98 Å. O2- is bonded in a water-like geometry to two equivalent Ba2+ and two H1+ atoms. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four equivalent Ba2+ atoms. In the second Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three equivalent Ba2+ atoms.
