In the title compound, [Rh(C₁₀H₉O₂)(CO)₂], a distorted square-planar coordination geometry is observed around the Rh^I atom, formed by the O atoms of the bidentate ligand and two C atoms from the carbonyl ligands. The Rh^I atom is displaced from the plane through the surrounding atoms by 0.017 Å. In the crystal, C-HO interaction is observed between a methyl group of the bidentate ligand and a carbonyl O atom. Metallophilic interactions [3.308 (3) and 3.461 (3) Å] between neighbouring Rh^I atoms are encountered in the crystal, resulting in the formation of a metal chain along the b-axis direction.
