MULTIPLE-METAL COMPLEX-CONTAINING COMPOUND AND METAL COMPLEX, AND MANUFACTURE METHODS THEREFOR, AND EXHAUST GAS PURIFICATION CATALYST MANUFACTURE METHOD USING THE SAME

摘要

A multiple-metal complex-containing compound in accordance with an embodiment has a plurality of metal complexes in each of which a ligand is coordinated to one metal atom or a plurality of metal atoms of the same kind. The plurality of metal complexes are bound to each other via a polydentate ligand that substitutes partially the ligands of the two or more metal complexes, and have 2 to 1000 metal atoms.
