QUADRUPOLAR [1(4)] (META-ORTHO)(2) AZOLOPHANES - INTRAMOLECULAR C-H-CENTER-DOT-CENTER-DOT-CENTER-DOT-N AND TO WATER C-H-CENTER-DOT-CENTER-DOT-CENTER-DOT-O HYDROGEN BONDING REVEALED BY X-RAY DIFFRACTION

摘要

The first X-ray crystallographic diffraction of an example of the title heterophanes built up from heterocyclic betaine subunits is reported and its quadrupolar character is confirmed. The crystal packing of 2 . 4H(2)O is mainly governed by hydrogen-bonding networks, strong intermolecular interactions with water together with weak interactions, either intramolecular or with water.
