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