Two Novel Heteropolyniobates Using TeO₃²– as Template and Linker

By adopting different crystal growth methods, two novel organic-inorganic hybrids, [{Cu(phen)}₆(H₂O)(Te₅Nb15.5Cu0.5O₅₇)]3.5- and its dimer, have been successfully synthesized. These are fabricated by simple compound reactions and directed by the tellurite anions, which act as heteroanion templates and linkers, as well as a pendant ligand. The compounds were characterized by IR spectra, UV/vis, thermogravimetric analysis, and single crystal X-ray diffraction. Furthermore, the solution behavior was also investigated.
