The preparation and dynamic behaviour of platinum(IV) derivatives of macrocyclic sulphides; the X-ray crystal structure of fac-[PtMe3SCH2CH2SCH2CH2SCH2CH2]Cl·2H2O

Abstract

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.
