Materials Data on Ba(H2O3)2 by Materials Project

Abstract

Ba(H2O3)2 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of two Ba(H2O3)2 ribbons oriented in the (0, 0, 1) direction. Ba is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Ba–O bond distances ranging from 2.75–2.85 Å. There are two inequivalent H sites. In the first H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.98 Å. In the second H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.98 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to two equivalent Ba and one O atom. The O–O bond length is 1.35 Å. In the second O site, O is bonded in a 1-coordinate geometry to one Ba and one O atom. In the third O site, O is bonded in a water-like geometry to one Ba and two H atoms.
