The complex (R = ME or Et) reacts with an excess of RNCS (R = Ph or p-MeC6H4) to give the thiazetidine complexes > obtained by formal insertion of the heterocumulene molecule into the Re-OR bond.The crystal structure of the complex > was determined by X-ray crystallography.The compound is triclinic, space group P1 with a = 12.991(5), b = 11.394(5), c = 10.024(5) Angstroem, α = 93.53(3), β = 100.29(3), γ = 77.74(3) degree, and Z = 2.The structure was refined to R = 0.035 for 4626 independent reflections.The Re atom is six-co-ordinate distored octahedral.The organic ligand is chelated through the nitrogen and sulphur atoms and makes with the metal a roughly planar four-membered ring.Selected bond distances are: Re-O 1.671(4), Re-P 2.488(2), Re-Cl 2.381(2) and 2.437(2), Re-N 2.087(5), and Re-S 2.406(2) Angstroem.
