Abstract

The charged-component complexes H 3 O + • 18-crown-6.CF 3 SO 3 − , H 3 O + • 18-crown-6.SbF 6 − , and (H 3 O + • 18-crown-6) 2• PtCl 6 2− have been isolated and studied by infrared and Raman spectroscopy, along with the previously reported H 3 O + • 18-crown-6 • C1O 4 − and H 3 O + • 18-crown-6 • PF 6 − adducts. Also synthesized were the corresponding derivatives with BF 4 − and PtCl 6 2− anions, using dicyclohexano-18-crown-6 as the host for the hydronium ion.
