Abstract

New heteroatom polyoxovanadates (POVs) were synthesized by applying a water-soluble high-nuclearity cluster as new synthon. The [V15Sb6O42]6− cluster shell exhibiting D3 symmetry was in situ transformed into completely different cluster shells, namely, the α-[V14Sb8O42]4− isomer with D2d and the β-[V14Sb8O42]4− isomer with D2h symmetry. The solvothermal reaction of {Ni(en)3}3[V15Sb6O42(H2O)x]⋅15 H2O (x=0 or 1; en=ethylenediamine) in water led to the crystallization of [{Ni(en)2}2V14Sb8O42]⋅5.5 H2O containing the β-isomer. The addition of [Ni(phen)3](ClO4)2⋅0.5 H2O (phen=1,10-phenanthroline) to the reaction slurry gave the new compound {Ni(phen)3}2[V14Sb8O42]⋅phen⋅12 H2O with the α-isomer. Both transformation reactions are complex due the change of symmetry, the chemical composition, and rearrangement of the VO5 square pyramids and Sb2O5 handle-like moieties.
