The title Cu(II) complex, [Cu(C(9)H(9)O(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains two 4-ethylbenzoate (PEB) ligands, two monodentate diethylnicotinamide (DENA) ligands and two water molecules. The four O atoms in the equatorial plane around the Cu(II) ion form a slightly distorted square-pl...

Sumario: | The title Cu(II) complex, [Cu(C(9)H(9)O(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains two 4-ethylbenzoate (PEB) ligands, two monodentate diethylnicotinamide (DENA) ligands and two water molecules. The four O atoms in the equatorial plane around the Cu(II) ion form a slightly distorted square-planar arrangement, while the distorted octahedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. Intramolecular O—H⋯O hydrogen bonds link the water molecules to the carboxylate groups. The dihedral angles between the carboxylate groups and the adjacent benzene rings are 4.6 (3) and 3.7 (2)°, while the pyridine rings and the benzene rings are oriented at dihedral angles of 6.82 (11) and 3.63 (14)°. In the crystal, intermolecular O—H⋯O hydrogen bonds link the molecules into chains propagating along [010]. C—H⋯O interactions and a π–π contact between the pyridine rings [centroid–centroid distance = 3.469 (2) Å] are also observed. |
