N2 - The X-ray crystal and molecular structure of [I-L 4+]3+ 3I-.3MeCN·H2O, L = N4Me4(C6H12)6, shows one iodide anion to be encapsulated symmetrically into the spherical intramolecular cavity of the macrotricycle L4+ and held in place by the electrostatic potential of the four quaternary ammonium sites arranged at the corners of an almost perfect tetrahedron; the N+⋯I- distances average to 4.54(2) Å whereas the distances between iodide and the carbon atoms of the [CH2]6 chains are of van der Waals type or longer.
