Crystal structure of poly[[aqua-(μ-2,3-di-hydro-thieno[3,4-b][1,4]dioxine-5,7-di-carboxyl-ato-κ2O5:O7)[μ-di(pyridin-4-yl)sulfane-κ2N:N']zinc] 0.26-hydrate].
The crystal structure of the title polymer, {[Zn(C8H4O6S)(C10H8N2S)(H2O)]·0.26H2O}n, is characterized by a layered arrangement parallel to theabplane. The zinc cation is five-coordinated in a slightly distorted trigonal-bipyramidal coordination environment defined by two pyridine ligands, two carboxyl-ate groups of two thio-phene di-carboxyl-ate ligands, and by one water mol-ecule. The ethyl-ene bridge in the dioxine ligand is disordered over two sets of sites [occupancy ratio 0.624 (9):0.376 (9)]. Several hydrogen-bonding inter-actions of the types O-H⋯O, C-H⋯O, C-H⋯S and C-H⋯N ensure the cohesion within the crystal structure.
