Bis(methacrylato-κO)bis­(2,4,6-trimethyl­pyridine-κN)copper(II)

In the monomeric title complex, [Cu(C(4)H(5)O(2))(2)(C(8)H(11)N)(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-CuN(2)O(2) 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 CuN(2)O(2) 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 =CH(2) and –CH(3) groups of the carboxyl­ate anion may be disordered, but the disorder could not be resolved in the present experiment. Several intra­molecular C—H⋯O inter­actions occur. In the crystal, mol­ecules are linked by weak C—H⋯O hydrogen bonds, generating chains propagating in [100].
