and 2-(1-naphthyl)ethyl (13). Solid-state structures are reported for six examples of alkalimetal complexes in which the cation is pi-coordinated by phenyl, phenol, or indole. Indole-containing crown, 7, adopts a similar conformation when bound by NaI, KI, KSCN, or KPF(6). In each case, the macroring and both arenes coordinate the cation; the counteranion is excluded from the solvation sphere. NMR measurements
