Description/Abstract
The complexes fac-[M(CO)(3)L-3] (M = Mo or W, L-3 = MeC(CH2SMe)(3), MeC(CH2SeMe)(3) or MeC(CH2TeMe)(3)) have been prepared from [M(CO)(3)(MeCN)(3)] and characterised by analysis, FAB mass spectrometry, IR, H-1, C-13{H-1}, Se-77, Te-125 and Mo-95 NMR spectroscopies. The complexes are prone to decomposition in solution into tetracarbonyls, and attempts to isolate [Cr(CO)(3)L-3] have been unsuccessful. The complexes cis-[Cr(CO)(4){eta(2)-MeC(CH2SMe)(3)}], cis-[Mo(CO)(4)(eta(2)-MeC(CH2SeMe)(3)}] and the robust [M(CO)(4)(S-3)] (M = Cr, Mo or W, S-3 = 1,4,7-trithiacyclononane or 1,4,7-trithiacyclodecane) have been similarly characterised.
