Neutral zinc complexes [ZnL2L′] of a series of methyl-substituted N-2-pyridylsulfonamide ligands (HL) and 1,10-phenanthroline or 2,2′-bipyridine (L′) have been synthesised by electrochemical oxidation of anodic zinc metal in an acetonitrite solution of the ligand and the coligand. The compounds obtained have been characterised by microanalysis, IR and 1H NMR spectroscopy, LSI mass spectrometry studies and some of the mixed complexes by single-crystal X-ray diffraction. The crystal structures show different octahedral environments around the metal (N6 or N4O2) depending on the position of the substituent on the pyridine ring.
