The asymmetric unit of the title barium coordination polymer, [Ba(C 6 H 2 N 3 O 7 ) 2 (C 2 H 6 OS)] 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 μ 2 -monoatomic bridging binding mode of both types of ligands results in the formation of an infinite chain of face-sharing {BaO 10 } polyhedra flanked by the remaining parts of the 2,4,6-tri-nitro-phenolato and DMSO ligands. In the one-dimensional coordination polymer, parallel chains are inter-linked with the aid of C—H?O hydrogen bonds.
