A new polymorph of N-(6-methylpyridin-2-yl)mesitylenesulfonamide

A new polymorph is reported of the pharmaceutically active sulfapyridine derivative, N-(6-methylpyridin-2-yl)mesitylenesulfonamide, in the zwitterionic form 2-methyl-6-{[(2,4,6-trimethylbenzene)sulfonyl]azanidyl}pyridin-1-ium, C15H18N2O2S. The observed dimorphism is solvent dependent. The phase described previously [Beloso, Castro, Garcia-Vazquez, Perez-Lourido, Romero and Sousa (2003). Z. Anorg. Allg. Chem. 629, 275-284] crystallizes from ethanol and several other organic solvents, whereas the new form described here is obtained as a phase-pure product from methanol. The molecules in both dimorphic phases are very similar and adopt the conformation which is also predicted for an individual molecule by force field calculations. However, the two forms differ in their packing and hydrogen bonding. Results from solvent-assisted grinding indicate that the new form is less stable than the previously published phase.

Flexidentate behaviour of 2-pyridylsulfonamides - Direct electrochemical synthesis and spectroscopic and x-ray characterisation of neutral copper(II) complexes of N-(2-pyridyl)sulfonamides

Copper complexes with potentially bidentate N-(2-pyridyl)-sulfonylamide ligands have been synthesised by the electrochemical oxidation of the metal in an acetonitrile solution of the neutral amide and additional bidentate N-N coligands. The compounds have been characterised by microanalysis and EPR, vibrational and electronic spectroscopy. In representative cases the structures were also determined by X-ray diffraction methods. Various coordination behaviour is found for the ligands, which act in a N, N′-bidentate or N, O-bidentate manner, the latter giving abnormally short Cu-O bonds. Wiley-VCH Verlag GmbH & Co.
