Synthesis and Characterization of Rhenium Thiolate Complexes - Crystal and Molecular-Structures of (Nbu(4))(Reo(H2O)Br-4))Center-Dot-2H(2)O, (Bu(4)N)(Reobr4(Opph(3))), (Reo(Sc5H4N)(3)), (Reo(Sc4H3N2)(3))(Reo(Oh)(Sc5H4N-3,6-(Sime(2)Bu(T))(2))(2)), (Re(N2Coc6H5)(Sc5H4N)Cl(Pph(3))(2)),and (Re(Pph(3))(Sc4H3N2)(3))
The syntheses and characterizations of six monomeric rhenium thiolate complexes and the structural characterization of two useful rhenium starting materials are presented. Pyridine-2-thiol (1) and its derivatives 3-(trimethylsilyl)pyridine-2-thiol (2), 3,6-bis(dimethyl-tert-butylsilyl)pyridine-2-thiol (3), and pyrimidine-2-thiol (4) were reacted with [Bu(4)N][ReOBr4(H2O)]. 2H(2)O (5), [Bu(4)N][ReOBr4(OPPh(3))] (6), [ReO2(C5H5N)(4)], and [Re{N2CO(C6H5)}Cl-2(PPh(3))(2)] to give [ReO(C5H4NS)(3)] (7), [ReO(C8H12NSiS)(3)] (8), [ReO(OH)(C11H20NSi2S)(2)] (9), [Re{N2CO(C6H5)}Cl(PPh(3))(2)(C5H4NS)] (10), [ReO(C4H3N2S)(3)] (11), and [Re{P(C6H5)(3)}(C4H3N2S)(3)] (12).
