Abstract

BaC₆X₂O₄ · 3H₂O (X = Cl, Br) crystallizes in the orthorhombic space group Cmca. 4 of the 8 oxygen atoms around Ba²⁺ belong to two different dianions, chelating Ba²⁺. In this way 1-dimensional corrugated chains are formed, interlinked by two oxygen atoms of neighbouring chains, thus forming layers. This interconnection is of polar character within a layer. The interlinking oxygen atoms have one carbon- and two Ba²⁺ neighbours. CN 8 is completed by two water molecules. The latter and a further water molecule situated between the layers may be removed reversibly in a topochemical reaction without destruction of the structure.
