Abstract: The metal atom of the Cr(CO)₃ unit of the title compound, [Cr(C₁₇H₁₄O₄)(CO)₃], is coordinated to the methoxyphenyl ring of the isoflavone ligand; the Cr(CO)₃ unit exhibits a three-legged piano-stool conformation. The aromatic ring of the methoxyphenyl group is twisted by 42.49 (9)° with respect to the -pyrone ring. In the fused-ring, the dihedral angle between the phenylene and -pyrone rings is 3.08 (13)°.
