[N,N'-Bis(salicylidene)-1,4-diiminobutane]copper(II)

In the title compound, {2,2'-[1,4-butanediylbis(nitrilomethylidyne)]diphenolato-O,N,N',O'}copper(II), [Cu(C₁₈H₁₈N₂O₂)], the Cu atom is coordinated by an N₂O₂ donor set from the imine-phenol ligand in a distorted planar coordination geometry, with the two phenolate O atoms being deprotonated. The Cu-O bond lengths are 1.898 (3) and 1.903 (3) Å, and the Cu-N bond lengths are 1.941 (3) and 2.000 (3) Å. The angles O1-Cu-N2 and O2-Cu-N1 are 144.0 (1) and 153.3 (1)°, respectively. The dihedral angle between the two salicylaldiminato groups around the central Cu atom is 42.7 (1)°.
