The complexes fac-[PtMe3L]Cl, where L = 1,4,7-trithiacyclonane (1), 1,4,7,10-tetrathiacyclododecane (2), and 10-oxa-2,4,7-trithiacyclododecane (3), have been prepared, and the X-ray crystal structure of (1), isolated as a dihydrate, has been obtained; variable-temperature 1H and 13C-1H} n.m.r. studies of (2) have revealted a novel ligand commutation involving exchange between metal-co-ordinated and unco-ordinated sulphur atoms of the macrocycle.
