(L2), and a new nine-membered NS2 macrocycle bearing a pendant 2-methylpyridyl arm 7-(2-methylpyridyl)aza-1,4-dithiacyclononane (L3). Complexes 1–5 were characterized by IR spectroscopy, ESI-MS(+), elemental analysis and single-crystal X-ray diffraction (for 2, 4 and 5). The oxidation catalytic properties of 1–5 were evaluated in two model reactions: (i) the mild oxidation of cyclohexane to cyclohexanol
