Abstract
Rhenium (V) ionic liquids of formula [BzEt(3)N][ReOCl3 (MBT)(tri)] and [Et3N][ReOCl3(amino)] (BzEt(3)N = benzyltriethyl-ammonuim, Et3N = triethylammonium, MBT = mercaptobenzothiazole, Tri = 1, 2, 4-triazole and amino = amino thiazole) were synthesised by reaction between [BzEt(3)N][ReOCl4] and [Et3N][ReOCl4] precursors and free ligands, in the presence of triethylamine. These ionic liquid complexes have been characterised by elemental analysis, spectroscopy (IR, H-1-C-13 NMR, MS) and thermogravimetric studies. Geometry optimisation of [Et3N][ReOCl3(amino)] has been carried out using DFT and the predicted IR spectrum of the geometrically-optimised structure shows good agreement with experimental values.
