    The crystal structure of the bicyclic hexaamine complex [Cu(fac-Me 5-tricosane-N6)](ClO4)2· H2O (fac-Me5-tricosane-N6 = facial-1,5,9,13,20-pentamethyl-3,7,11,15,18,22-hexaazabicyclo[7.7.7]tricosane) at 100 K defines an apparently tetragonally compressed octahedral geometry, which is attributed to a combination of dynamic interconversion and static disorder between two tetragonally elongated structures sharing a common short axis. This structure is fluxional at 60 K and above as shown by EPR spectroscopy. Aqueous cyclic voltammetry reveals that a remarkably stable CuI form of the complex is stabilised by the encapsulating nature of the expanded cage ligand.
