Abstract: In the title compound, [Co(C₇H₅O₃)₂(C₁₄H₁₂N₂)], the Co^II ion is five-coordinated by two N atoms from one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and three O atoms from two 2-hydroxybenzoate anions in a distorted trigonal bipyramidal geometry. The carboxylate group of one of the two 2-hydroxybenzoate anions is monodentate with a normal Co-O distance [1.9804 (18) Å], while the other is bidentate with two longer Co-O bonds [2.1981 (18) and 2.1359 (19) Å]. The crystal structure is stabilized by aromatic - stacking interactions [centroid-centroid distances of 4.0380 (3) and 3.8216 (3) Å between dmphen/dmphen and benzene/dmphen rings, respectively] and C-H(benzene) interactions.
