Crystal structure of a binuclear five-co-ordinate copper(II) complex with tetra-amine macrocyclic ligands and single chloride bridge

Hydrogen bonding between tet b and perchlorate ions stabilizes [Cu(tet b)]2Cl3+ which contains trigonal bipyramidal co-ordinate Cu2+ with an almost linear Cu–Cl–Cu bridge and with the tet b ligand in its most stable, folded form.
