Aqua(1,5,8,12-tetramethyl-1,4,8,11-tetraazacyclotetradecane-N,N',N'',N''')copper(II) Diperchlorate

Abstract

The CuII ion in the title compound, [Cu(C14H32N4)(H2O)](ClO4)2, is five-coordinate in a distorted square-pyramidal geometry with the four N atoms of the macrocyclic ligand equatorial and the O atom of the aqua group axial. The quadridentate ligand adopts its most stable conformation with the two six-membered rings in chair conformations and the two five-membered rings in gauche conformations. The complex has a 1SR,4SR,8SR,11SR configuration for the four chiral N-atom centers and a 5RS,12RS configuration for the two chiral C-atom centers.
