Title: Binuclear metal complex, metal complex dye, photoelectric conversion element, and photochemical battery

Abstract: A novel binuclear metal complex according to the present invention is an asymmetric binuclear metal complex represented by the general formula: (L.sup.1).sub.2M.sup.1(BL)M.sup.2(L.sup.2).sub.2(X).sub.n, wherein M.sup.1 and M.sup.2, which may be identical or different, represent a transition metal; L.sup.1 and L.sup.2, which are different, represent a chelate ligand capable of polydentate coordination and two L.sup.1s may be different and two L.sup.2s may be different; BL represents a bridge ligand having at least two heteroatom-containing cyclic structures, the heteroatoms contained in the cyclic structures being ligand atoms coordinating to M.sup.1 and M.sup.2; X represents a counter ion; and n is the number of counter ions needed to neutralize the charge of the complex. And the binuclear metal complex is useful as a metal complex dye.
