Formation of Extended Tapes of Cyclic Water Hexamers in an Organic Molecular Crystal Host

Abstract

An icelike chair conformation is adopted by the cyclic water hexamers found in an organic inclusion complex. Self-assembly of the hexamers into one-dimensional tapes (see picture), which interact very weakly with the organic host, confers on them characteristics similar to those of liquid water, as attested by FT-IR spectroscopy.
