Methyltrioxorhenium(VII), CH{sub 3}ReO{sub 3} (1), undergoes condensation reactions with aromatic bidentate ligands of type HO{hor ellipsis}X (X = N, NH{sub 2}, OH) to yield products with strongly ligand-dependent structures. Mild conditions are characteristic of these condensation reactions. Thus, reactions of 1 with catechols 1,2-(HO){sub 2}C{sub 6}H{sub 2}RR{prime}-3,4 in the presence of pyridine give compounds 2a-c of general formula CH{sub 3}Re(O){sub 2}(1,2-O{sub 2}C{sub 6}H{sub 2}RR{prime}-3,4)(NC{sub 5}H{sub 5}) in high yields. The single-crystal X-ray diffraction study of the parent catecholato derivative 2a (R = R{prime} = H) reveals an octahedral ligand sphere around the rhenium atom, with cis oxo ligands and the pyridine in trans position with respect to the methyl group.
