Bis(chlorido)(dimethyl­sulfoxide-κO)barium(II)

The title compound, [BaCl₂(C₂H₆SO)], forms a Ba₆Cl₉ cluster in which the BaCl₂ units are connected via dimethyl­sulfoxide (DMSO) and chloride bridges. The central Cl atom of the Ba₆Cl₉ cluster is located on a threefold inversion axis and is coordinated octa­hedrally to six barium cations. In the crystal, the clusters are arranged in rows, which are inter­connected by the DMSO mol­ecules, forming a three-dimensional network.
