چکیده
In the title compound, [Co(C(7)H(5)O(2))(2)(C(5)H(6)N(2))(2)], the Co(II) atom is hexa-coordinated by four O atoms from two benzoate anions, and two N atoms from two 2-amino-pyridine mol-ecules, resulting in a distorted octa-hedral geometry. Both benzoate anions act as bidentate ligands and both 2-amino-pyridine mol-ecules are coordinated to the metal through their pyridyl N atoms. The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds, C-H⋯π, and π-π stacking inter-actions involving benzoate anions and 2-amino-pyridine mol-ecules.
