Five new rhenium(III) complexes of the general formula ReCl 2(RFCOCHCORF)(PPh3)(OPPh 3), where RF = CF3 (I), C2F 5 (II), C3F7 (III), C4F9 (IV), and CF3CFOC3F7 (V), were synthesized. The known rhenium(V) complex ReOCl2(OC2H5) (PPh3)2, which can readily be obtained from metallic rhenium, was used as a precursor. Two polymorphous modifications of compound I were found and studied by X-ray diffraction analysis. The thermal properties of the synthesized complexes were characterized by the DTA-TG method.

The binuclear nitropyrazole compound [Re2O3Cl2(PPh3)2(C 3H2N3O2)2] (3) was synthesized by refluxing [ReOCl2(OEt) (PPh3)2] and 2-nitropyrazole in ethanol for 12 h. The octahedral {ReO2N2ClP} sites are linked by two bridging nitropyrazoles and an oxo group, with an Re-O-Re angle of 124.7(6)o. Compound 3 is electrochemically active, displaying a reversible one electron reduction at - 0.55 V with respect to Ag/Ag+. Crystal data: C36H34Cl2N6O7P 2Re2 (3), monoclinic C2/c, a = 32.569(7), b = 9.624(2), c = 29.151(6) A, β = 109.33(3)o, V = 8622(3) A3, Z = 8, Dcalc = 1.799 g cm-3, structure solution and refinement based on 3364 reflections converged at R = 0.056.

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 [Bu4N][ReOBr4(H2O)]·2H2O (5), [Bu4N][ReOBr4(OPPh3)] (6), [ReO2(C5H5N)4], and [Re{N2CO(C6H5)}Cl2(PPh 3)2] to give [ReO(C5H4NS)3] (7), [ReO(C8H12NSiS)3] (8), [ReO(OH)(C11H20NSi2S)2] (9), [Re{N2CO(C6H5)}Cl(PPh3) 2(C5H4NS)] (10), [ReO(C4H3N2S)3] (11), and [Re{P(C6H5)3}(C4H3N 2S)3] (12).
