The antimonato-polyoxovanadate {Ni(en)}[VSbO(HO)]·ca.15HO was utilized as a synthon for the solvothermal in situ generation of the new compound {Ni(phen)}[{Ni(en)}VSbO(HO)]·19HO, a rearrangement induced by ligand metathesis. While in the precursor structure cations and anions are isolated, the solid-state structure of the product is characterized by 1D chains consisting of alternating [VSbO(HO)] cluster shells and [Ni(en)] units covalently linked to neighboring clusters via terminal oxygen atoms. Water clusters composed of sixteen hydrogen-bonded HO molecules are located in void spaces of the structure. The magnetic properties indicate weak antiferromagnetic interactions of the bridging Ni center and adjacent polyoxovanadate anions, as well as small magnetic anisotropy of the individual Ni centers.
