Pyridine-2-sulfonates as Versatile Ligands for the Synthesis of Novel Coordinative and Hydrogen-Bonded Supramolecules

The reactions of 3-methylpyridine-2-sulfonic acid (3-mpSO3H) with CuII and 4-methylpyridine-2-sulfonic acid (4-mpSO3H) with ZnII in water formed one-dimensional infinite coordination polymers, [Cu(3-mpSO3)2]n (1) and [Zn(4-mpSO3)2]n (2). Similarly, two-dimensional hydrogen-bonded supramolecules of stoichiometries, [ML 2(H2O)2] [L = 3-methylpyridine-2-sulfonate (3-mpSO3), M = Mn (3), Fe (4), Co (5), Zn (6); L = 5-methylpyridine-2-sulfonate (5-mpSO3), M = Zn (7); L = pyridine-2-sulfonate (PySO3), M = Zn (8); L = 4-mpSO3, M = Co (9)], [Ni(3-mpSO3)2(H2O) 2]·H2O (10) and the one-dimensional hydrogen-bonded network [VO(acac)(3-mpSO3)(H2O)] (11) (acac = acetylacetonate) have been prepared. The ligands are tridentate [N,O-chelating-Cu-μ-O-bridging] in 1 and 2, while in all the other compounds the N,O-chelating and uncoordinated O atoms are engaged in intermolecular hydrogen bonding leading to the formation of hydrogen-bonded networks. The geometry around each metal center is octahedral (9) or distorted octahedral (1-8, 10 and 11). The compounds 3-8, and 10 showed novel π-π stacking interactions, not shown by 9 and 11. The magnetic behavior of 3 and 11 indicates lack of any intermolecular magnetic interactions. The position of the substituents in the pyridyl ring and Jahn-Teller effect (CuII) appear to determine the stacking interactions as well as the density of ligands with regard to the formation of coordinative and hydrogen-bonded supramolecules.
