Abstract: In the monomeric title complex, [Cu(C₄H₅O₂)₂(C₈H₁₁N)₂], the Cu^II atom lies on a centre of inversion. Its coordination by two substituted pyridine ligands and two carboxylate anions leads to a slightly distorted trans-CuN₂O₂ square-planar geometry. The dihedral angle between the mean planes of the pyridine (py) ring and the carboxylate group is 74.71 (7)°. The dihedral angles between the planar CuN₂O₂ core and the py ring and carboxylate plane are 67.72 (5) and 89.95 (5)°, respectively. Based on the refined C=C and C-C bond lengths, the terminal =CH₂ and -CH₃ groups of the carboxylate anion may be disordered, but the disorder could not be resolved in the present experiment. Several intramolecular C-HO interactions occur. In the crystal, molecules are linked by weak C-HO hydrogen bonds, generating chains propagating in [100].
