Abstract

The title compound methyltrioxorhenium, (CH3ReO3, 1), reacts with 8hydroxyquinoline at room temperature to give the dinuclear ReVII complex [CH3Re(O)2(8oxyquinoline)]2O (2) in 90% yield. A single crystal X-ray diffraction study has shown that 2 has a dimeric octahedral structure with a total of four terminal oxo ligands and one bridging oxygen atom. By contrast, the more complex condensation reaction of 1 with 2-hydroxyaniline gives the mononuclear ReVII compound CH3Re(O)(2-OC6H4NH)2 (3) in 60% yield.
