The five-coordinate CuIIatom in the title complex [CuCl2(C16H19N3)]·0.5C4H10O, adopts a near-ideal square-pyramidal geometry (τ-5 = 0.01). The apical Cu—Cl distance is 0.2626 (6) Å longer than the basal Cu—Cl distance. Weak C—H...Cl interactions between pyridine rings and the Cl atoms of adjacent complex molecules are present. The solvent molecule, located on a twofold rotation axis, is situated in the voids of this arrangement. Copper atoms coordinated by tridentate nitrogen-containing ligands have been found to be excellent promoters of Atom Transfer Radical Addition (ATRA) reactions.

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.
