Trapping of Octameric Water Cluster by the Neutral Unclosed Cryptand Environment
journal contribution
posted on 2014-10-01, 00:00 authored by Kajetan Dąbrowa, Magdalena Ceborska, Janusz JurczakUnclosed cryptands (UCs) are neutral
and easily accessible compounds
with precisely defined spatial arrangement of various functional groups.
They readily form crystals with a unusually high packing efficiency
(≥0.8), thus providing a well-suited 3D-framework for study
of supramolecular assemblies. Herein, one example of the discrete
eight-membered water cluster trapped in the matrix of UC 1 is presented.
X-ray, ATR FT-IR, and DFT studies indicate extraordinary stability
of this assembly, which originated from the cumulative interplay of
many noncovalent interactionshydrogen bonds and London dispersion
forces.
