catena-Poly[barium(II)-μ₂-(dimethyl sulfoxide)-κ² O:O-bis-(μ₂-2,4,6-tri-nitro-phenolato-κ⁴ O ²,O ¹:O ¹,O ⁶)].

ABSTRACT: The asymmetric unit of the title barium coordination polymer, [Ba(C₆H₂N₃O₇)₂(C₂H₆OS)] _n , consists of a barium cation (site symmetry m) and a dimethyl sulfoxide (DMSO) ligand (point group symmetry m) and a 2,4,6-tri-nitro-phenolate anion located in general positions. The S atom and the methyl group of DMSO are disordered over two sets of sites. The DMSO ligand bridges a pair of Ba^II atoms resulting in a chain extending parallel to the a axis. The unique 2,4,6-tri-nitro-phenolate anion also bridges a pair of Ba^II ions via the phenolic oxygen atom, with each Ba^II being additionally bonded to an oxygen atom of an adjacent nitro group. The
