Abstract: The RhIII ion in the title compound, [Rh(C12H6N2O4)(C12H7N2O4)], is coordinated by four N atoms and two O atoms from two chelating ligands L and HL (H2L = 2,2'-bipyridine-6,6'-dicarboxylic acid) to form a distorted octahedral geometry. Face-to-face -stacking interactions are observed between inversion-related pyridine rings, with a centroid-to-centroid distance of 3.581 (1) Å [the perpendicular distance between the rings is 3.3980 (7) Å]. Intermolecular O-HO hydrogen bonds link adjacent molecules into one-dimensional supramolecular chains along the c axis, while several intermolecular C-HO interactions are also observed.
