The first mononuclear Rev complex with four pyrazole ligands, viz., [Re(O)(OMe)L-4]Br-2 (L is 3,5-dimethylpyrazole), and its molecular adduct with L, viz., [Re(O)(OMe)L-4]Br-2.L.4H(2)O, were synthesized. The complex is resistant to hydrolysis in a neutral aqueous solution. The structure of the adduct was established by X-ray diffraction analysis.

Kinetic parameters are reported for catalysis of the aquation of the hexachlororhenate(IV) anion by mercury(II), thallium(III), cadmium(II), and indium(III), and of the hexabromorhenate(IV) anion by thallium(III), in aqueous solution. Correlation of these kinetic results with stability constants for halogeno-complexes of the respective metal cations is discussed.
