The title molecule, [Zn2(C9H10NO2)4(C10H14N2O)2], is a centrosymmetric binuclear complex, with Zn atoms [Zn⋯Zn′ = 2.8927 (4) Å] bridged by four carboxylate groups from the dimethylaminobenzoate (DMAB) ligands. The four carboxyl O atoms around the Zn atom form a distorted square-planar arrangement; the distorted square-pyramidal coordination geometry is completed by the pyridine N atom of the N,N-diethylnicotinamide (DENA) ligand. The Zn atom is displaced by 0.3326 (2) Å from the plane of the four O atoms, with an average Zn—O distance of 2.0416 (12) Å. The dihedral angles between the carboxylate groups and the adjacent benzene rings are 5.31 (8) and 11.00 (9)°, while the pyridine ring is oriented at dihedral angles of 66.26 (6) and 37.88 (7)° with respect to the benzene rings. Weak intramolecular C—H⋯O and intermolecular C—H⋯π interactions are present.
