✦ Synopsis
A novel mode of containment for metal ions which participate in longer-range interactions with aryl rings (Ն 2.5 A ˚) is demonstrated in the preorganized cylindrical host 1. Three equatorial sulfur atoms in 1 hold metals in a trigonal planar ligand field between two apical benzene centroids at an M-Ar distance of about 3 A ˚. Evidence of an interaction between the π electrons and the metals is gained by 1 H NMR spectroscopy of the complexes, and support for the general descrip-
