In [Cu(C21H19N3)2](ClO4)2, two tridentate N-donor ligands coordinate to a copper(II) centre to give a distorted octahedral environment. The two ligands are approximately orthogonal, with an angle of 89.7 (2)° between the two CuN3 planes. One of the ligands lies further from the Cu atom, its Cu-Nimino distances (mean 2.31 Å) being 0.21 Å longer than the corresponding distances for the second ligand, an effect which is due to a Jahn-Teller distortion.
