[(4E,11E)-5,7,12,14-Tetrabenzyl-7,14-dimethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene]copper(II) bis(perchlorate)

The complete cation in the title compound, [Cu(C40H48N4)](ClO4)2, is generated by the operation of a crystallographic centre of inversion. The CuII ion exists in a tetragonally distorted trans-N4O2 coordination geometry defined by the four N atoms of the macrocyclic ligand and two weakly bound perchlorate-O atoms from two anions. The N—H atoms form intramolecular N—H...O(perchlorate) hydrogen bonds. Disorder was resolved in the –CH2–NH– portion of the macrocycle with the major component having a site-occupancy factor of 0.570 (6).
