The tritopic hexa-aza-macrocycle (1) binds three CuII ions in solution and leads in particular to the assembly of a trinuclear bis-µ3-hydroxo bridged complex whose crystalstructure has been determined; it may be considered as a cryptate of a cationic cluster [Cu3(OH)2]4+ held inside the macrocyclic cavity of the ligand.

cation complexation, although a multitude of new structures and properties may be expected in view of the role played by anionic species in chemical as well as in biological processes.' For instance, macropolycyclic ammonium salts yield katapinates2 and anion cryptate~;,-~ polyguanidinium and polyammonium salts act as anion complex one^;^^^ quaternary ammonium salts allow selective extraction and transport
The hexa-(p-n-dodecyloxybenzoyl) derivatives (1b), (2b), and (3b) of the macrocyclic polyamines [18]-N6, [24]-N6O2, and [27]-N6O3 display a liquidcrystal phase in which the macrocyclic units are stacked, forming a tubularmesophase.
