Materials Data on Ba(ClO)2 by Materials Project

Abstract

(BaO2Cl)2Cl2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four hydrochloric acid molecules and one BaO2Cl framework. In the BaO2Cl framework, Ba is bonded in a 4-coordinate geometry to four O and three equivalent Cl atoms. There are a spread of Ba–O bond distances ranging from 2.72–2.81 Å. There are a spread of Ba–Cl bond distances ranging from 3.24–3.33 Å. There are two inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to two equivalent Ba and one Cl atom. The O–Cl bond length is 2.41 Å. In the second O site, O is bonded in a distorted bent 120 degrees geometry to two equivalent Ba atoms. Cl is bonded to three equivalent Ba and one O atom to form a mixture of distorted corner and edge-sharing ClBa3O trigonal pyramids.
