Abstract
A novel binuclear metal complex according to the present invention is an asymmetric binuclear metal complex represented by the general formula: (L)M(BL)M(L)(X), wherein Mand M, which may be identical or different, represent a transition metal; Land L, which are different, represent a chelate ligand capable of polydentate coordination and two Ls may be different and two Ls 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 Mand M; 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.
