17—and the in,in geometries have been confirmed by X-ray crystallography. In complex 12, the silver atom is encapsulated in a hydrophobic cavity, and it experiences strong spin-spin coupling to the phosphorus atoms. In the cyclophanes 16 and 17 an inwardly directed hydroxyl group or fluorine atom is pressed against the lone pair of the opposing, inwardly directed phosphine.
