The title complex, {[Ni(C15H11N4O2S)(2)(C10H8N2)(H2O)(2)]center dot H2O}(n), was synthesized by the reaction of nickel chloride, 4-{[(1-phenyl-1H-tetrazol-5-yl)sulfanyl]methyl} benzoic acid (HL) and 4,4'-bipyridine (bpy) under hydrothermal conditions. The asymmetric unit contains two half Ni-II ions, each located on an inversion centre, two L- ligands, one bpy ligand, two coordinated water molecules and one unligated water molecule. Each Ni-II centre is six-coordinated by two monodentate carboxylate O atoms from two different L- ligands, two pyridine N atoms from two different bpy ligands and two terminal water molecules, displaying a nearly ideal octahedral geometry. The Ni-II ions are bridged by 4,4'-bipyridine ligands to afford a linear array, with an Ni center dot center dot center dot Ni separation of 11.361 (1) angstrom, which is further decorated by two monodentate L- ligands trans to each other, resulting in a one-dimensional fishbone-like chain structure. These one-dimensional fishbone-like chains are further linked by O-H center dot center dot center dot O, O-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds and pi-pi stacking interactions to form a three-dimensional supramolecular architecture. The thermal stability of the title complex was investigated via thermogravimetric analysis.
