The Cu(II) atom in the title complex, [Cu(C11H29N5)]-(ClO4)3, is five-
coordinate and is in a distorted trigonal-bipyramidal conformation. Th
e longer Cu(equatorial)-N bond distances compared to the Cu(axial)-N d
istances indicate the steric influence of the two N-methyl groups. The
ligand is in its stable conformation with the three five-membered che
late rings in stable skew forms and the six-membered ring in a stable
chair form.
