In the crystal structure of the title mononuclear CuIIcomplex, [Cu(C11H16N3O2)(NO3)]·0.25C2H5OH, the complex molecules are linked by N—H...O and O—H...O hydrogen bonds, forming a dimer with an approximate non-crystallographic twofold rotation axis of symmetry. In the monomeric unit, the Cu2+ion exhibits a distorted square-pyramidal configuration, whereby the anionic [HL]−Schiff base ligand binds in a tetradentate fashionviathe O and the three N atoms which all are approximately coplanar. The O atom of a nitrate anion occupies the fifth coordination site, causing the CuIIatom to move slightly out of the approximate basal plane toward the bound nitrate group. The structure exhibits disorder of the ethanol solvent molecule.

The Mean

In the mononuclear copper(II) title complex, [Cu(C11H16N3O)(H2O)]Br, the CuIIatom is coordinated by one O and three N atoms of the Schiff base ligand that forms together with one water molecule a slightly distorted [CuN3O2] square-pyramidal polyhedron. The deviation of the CuIIatom from the mean equatorial plane is 0.182 (2) Å. The equatorial plane is nearly coplanar to the aromatic ring of the ligand [angle between planes = 10.4 (1)°], and the water molecule is situated in the apical site. All coordinating atoms (except the imine nitrogen) and the bromide ion contribute to the formation of the N—H...Br, O—H...Br and O—H...O hydrogen bonds, which link molecules into chains along [01-1].
