Deskripsi
The crystal structure of the title polymer, {[Zn(C8H4O6S)(C10H8N2S)(H2O)]·0.26H2O}n, is characterized by a layered arrangement parallel to the ab plane. The zinc cation is five-coordinated in a slightly distorted trigonal–bipyramidal coordination environment defined by two pyridine ligands, two carboxylate groups of two thiophene dicarboxylate ligands, and by one water molecule. The ethylene bridge in the dioxine ligand is disordered over two sets of sites [occupancy ratio 0.624 (9):0.376 (9)]. Several hydrogen-bonding interactions of the types O—H...O, C—H...O, C—H...S and C—H...N ensure the cohesion within the crystal structure.
