Abstract: In the title compound, [Cu(C₁₅H₁₁N₃O₃)(C₁₀H₈N₂)], the Cu^II atom is five-coordinated in a distorted square-pyramidal CuN₃O₂ geometry. The basal positions are occupied by three donor atoms from the tridentate Schiff base ligand and by one N atom from the 2,2'-bipyridine ligand. The axial position is occupied by the other N atom of the 2,2'-bipyridine ligand. The crystal structure is consolidated by weak C-HO hydrogen bonds. In addition, - interactions between adjacent pyridine rings (centroid-centroid distances = 3.238 and 3.313 Å) may also stabilize the crystal packing.
