In the monomeric title complex, [Cu(C 4H 5O 2) 2(C 8H 11N) 2], the Cu II atom lies on a centre of inversion. Its coordination by two substituted pyridine ligands and two carboxyl-ate anions leads to a slightly distorted trans-CuN 2O 2 square-planar geometry. The dihedral angle between the mean planes of the pyridine (py) ring and the carboxyl-ate group is 74.71 (7)°. The dihedral angles between the planar CuN 2O 2 core and the py ring and carboxyl-ate 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 carboxyl-ate anion may be disordered, but the disorder could not be resolved in the present experiment. Several intra-molecular C-H⋯O inter-actions occur. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, generating chains propagating in .
