Carballo, Rosa; Fernandez-Hermida, Nuria; Lago, Ana B.; Rodriguez-Hermida, Sabina; Vazquez-Lopez, Ezequiel M. published an article in 2012, the title of the article was Supramolecular networks through second-sphere coordination based on 1D metal-4,4′-dipyridyldisulfide coordination polymers and hydrogenfumarate or sulfonate anions.Quality Control of Pyridine-3-sulfonic acid And the article contains the following content:
Four H-bonded assemblies [M(dpds)2(OH2)2]A2·nH2O (A = anion) are described. These assemblies result from the 2nd-sphere coordination interactions between the 1-dimensional coordination polymers [M(dpds)2(OH2)2]2+, M = Zn(II), and Cu(II), dpds = 4,4′-dipyridyldisulfide, and the pyridine-3-sulfonate (3pySO3-) or hydrogenfumarate (Hfum-) anions. Significantly, supramol. structural variations are observed depending on the presence of H2O lattice mols., which formed discrete aggregates when the Hfum- anion was used. The effects of geometrical variations in the building blocks are also evident on using Jahn-Teller-distorted divalent Cu(II) ions or regular octahedral species based on Zn(II) ions. The 2nd-sphere effects on the stabilization of the compounds are illustrated by TGA experiments The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Quality Control of Pyridine-3-sulfonic acid
