There is provided a metal-containing azo compound suitably used for an recording layer of an optical medium, which is represented by at least one of the following general formulae:
wherein M(II) is a bivalent metal, X1 and X2 are each a residue that forms a monocyclic or polycyclic aromatic ring, Y1 and Y2 are each a residue that forms a nitrogen-containing aromatic heterocycle, and one residue is different from the other in at least one of a combination of X1 and X2, and a combination of Y1 and Y2; and there is also provided an optical recording medium of which recording layer comprises said metal-containing azo compound.
