The title compound, [Co2(C8H7O2)4(C7H10N2)2], crystallizes as a centrosymmetric dimer containing two CoII atoms bridged by four bidentate phenylacetate ligands in syn-syn bridging modes. Each CoII atom is five-coordinated by four O atoms from four different carboxylate ligands and the ring N atom of a 4-(dimethylamino)pyridine unit, generating a distorted square-pyramidal geometry in which the four O atoms form the basal plane and the N atom occupies the axial position. In the crystal, C-H...O interactions link the dinuclear complex molecules into a three-dimensional network.
