✦ Synopsis


It is generally believed [l] that vanadium(IV) perchlorate in acidic aqueous solution exists in the form WW2>51 2+. A unique feature of the ion is the multiple bond between V(IV) and one of the ligand oxygens giving a strong axial symmetry to the molecule. This results in three types of oxygens coordinated to a single positive ion center, 0

The rate of oxygen exchange between truns-[Re(py),02]+ and solvent water in py-pyH' buffer solution follows simple first-order kinetics and both oxygens are equivalent. The half-life for isotopic oxygen exchange is about 12 h at a pH of 5.0, 25"C, and [pyl = 0.10 M. The observed rate constant for ex
