Complex formation
and the coordination of zirconium with acetic acid were investigated
with Zr K-edge extended X-ray absorption fine structure spectroscopy
(EXAFS) and single-crystal diffraction. Zr K-edge EXAFS spectra show
that a stepwise increase of acetic acid in aqueous solution with 0.1
M Zr(IV) leads to a structural rearrangement from initial tetranuclear
hydrolysis species [Zr4(OH)8(OH2)16]8+ to a hexanuclear acetate species Zr6(O)4(OH)4(CH3COO)12.
The solution species Zr6(O)4(OH)4(CH3COO)12 was preserved in crystals by slow
evaporation of the aqueous solution. Single-crystal diffraction reveals
an uncharged hexanuclear cluster in solid Zr6(μ3-O)4(μ3-OH)4(CH3COO)12·8.5H2O. EXAFS measurements
show that the structures of the hexanuclear zirconium acetate cluster
in solution and the solid state are identical.
