(2,9-dimethyl-1,10-phenanthroline-κ2N,N′)bis(2-hydroxybenzoato)-κO;κ2O,O′-cobalt(II)

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) angstrom], while the other is bidentate with two longer Co-O bonds [2.1981 (18) and 2.1359 (19) angstrom]. The crystal structure is stabilized byaromatic pi-pi stacking interactions [centroid-centroid distances of 4.0380 (3) and 3.8216 (3) angstrom between dmphen/dmphen and benzene/dmphen rings, respectively] and C-H center dot center dot center dot pi(benzene) interactions.
