Abstract
The competition between ion–molecule and hydrogen bond interactions in K + (benzene) 1–5 (water) 1,2 is examined using infrared spectroscopic and mass spectrometric methods. The cation-π interaction and π-hydrogen bond play an important role in the structure of the mixed cluster ions. Important observations include: the preferential binding of benzene vs water to K + ; the “dehydration” of the potassium ion by benzene; and the observation of water acting as a double proton donor with π-hydrogen bonds to two benzenes.Keywords
