The reactions of tantalum butoxide with several organic diols gave novel net-worked alternative tantalum-organic moieties hybrid copolymers particles whose forms and sizes varied with the organic units. Electron transfer from aromatic groups to tantalum atom in the net-worked structures was demonstrated by the results of ESR spectra and ab-initio calculations.
