MeC(CH2SMe)3 or MeC(CH2SeMe)3, (L3) in anhydrous n-hexane or CH2Cl2 produced the extremely moisture sensitive complexes [TiX4(L3)]. These were characterised by microanalysis, IR, UV–Vis and variable temperature 1H,13C1H} and 77Se NMR spectroscopy. The NMR studies showed that in solution in CH2Cl2 the complexes contain L3 bound as bidentates, and that pyramidal inversion and exchange between the free and coordinated
