The Rh(III) ion in the title compound, [Rh(C(12)H(6)N(2)O(4))(C(12)H(7)N(2)O(4))], is coordinated by four N atoms and two O atoms from two chelating ligands L and HL (H(2)L = 2,2'-bipyridine-6,6'-dicarb-oxy-lic acid) to form a distorted octa-hedral geometry. Face-to-face π-stacking inter-actions 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]. Inter-molecular O-H⋯O hydrogen bonds link adjacent mol-ecules into one-dimensional supra-molecular chains along the c axis, while several inter-molecular C-H⋯O inter-actions are also observed.
