C–H⋯Cl− hydrogen bonds in solution and in the solid-state: HgCl2 complexes with cyclen-based cryptands

Abstract

Structural evidence is reported for C–H⋯Cl− hydrogen bonds in solution and in the solid state of HgCl2 complexes with cyclen-based cryptands. These cyclen-based cryptands (1) and (2) are bridged by di- and triethylene glycol units, respectively, between two aromatic rings. The X-ray structure indicates that the 2/HgCl2 complex contains an acetonitrile molecule in the cavity.
