Crystal structures of sandwich-type potassium cation complexes formed from benzo-15-crown-5-based ligand containing a chloromaleimide moiety†

Abstract

We developed a novel benzo-15-crown-5 (B15C5)-based organic ligand containing an N-phenylchloromaleimide moiety. Two geometrically different potassium cation (K⁺) complexes with a B15C5/K⁺/B15C5 sandwich structure were prepared and characterised via single-crystal X-ray diffraction.
