%X The tantalum complex [TaCp*Cl2{2,6(OOC)2py-κ2O,O}] (1) has been synthesized by reaction of [TaCp*Cl4], Cp* = η5-C5Me5, with 2,6-pyridinedicarboxylic acid. Complex 1 reacts with AgOTf, OTf = trifluoromethylsulfate, to yield the new tantalum carboxylate derivative [TaCp*Cl(OTf){2,6(OOC)2py-κ2O,O}] (2) or with KOH to render the dinuclear oxo compound [TaCp*(μ-O){2,6(OOC)2py-κ2O,O}] 2 (3). The reaction of 3 with H2O and HOTf gives the dinuclear hydroxo derivative [{TaCp*{2,6(OOC)2py-κ2O,O}}2(μ-OH)3](OTf) (5). The structures of complexes 1, 2, 3, and 5 have been established by X-ray diffraction methods.
