Porous supramolecular compound based on paddle-wheel shaped copper(ii)–adenine dinuclear entities

The reaction between CuCl2 and adenine in a non-aqueous solvent provides a 3D porous structure based on paddle-wheel [Cu2(µ-adenine)4Cl2]2+ cations and Cl− anions that are held together by a robust supramolecular hydrogen bonding network. The desolvated compound is able to host different guest molecules within the ∼6 Å diameter 1D channels.
