Bis(benzoato-κO,O')(2,9-dimethyl-1,10-phenanthroline-κN,N')cobalt(II).

In the title compound, [Co(C(7)H(5)O(2))(2)(C(14)H(12)N(2))], the Co(II) ion is located on a twofold rotation axis and is chelated by a 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and two benzoate anions in a distorted octa-hedral geometry. The crystal packing is stabilized by π-π inter-actions between parallel dmphen ligands of neighbouring mol-ecules, with a face-to-face distance of 3.411 (2) Å.

(2,9-Dimethyl-1,10-phenanthroline-κN,N')bis-(2-hydroxy-benzoato)-κO;κO,O'-cobalt(II).

In the title compound, [Co(C(7)H(5)O(3))(2)(C(14)H(12)N(2))], 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-hydroxy-benzoate anions in a distorted trigonal bipyramidal geometry. The carboxyl-ate group of one of the two 2-hydroxy-benzoate 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 π-π stacking inter-actions [centroid-centroid distances of 4.0380 (3) and 3.8216 (3) Šbetween dmphen/dmphen and benzene/dmphen rings, respectively] and C-H⋯π(benzene) inter-actions.
