coordination approach to construct supramolecularinclusionsolids with a variety of guest molecules. A novel type of a pillared double-layered host framework was constructed by a second-sphere coordination between the anion-directed ligand (L1 = N,N,N′,N′-tetra-p-methylbenzyl-ethylenediamine) and [CoCl4]2 − through weak C–H…Cl hydrogen-bonding interaction, and a variety of guest molecules, such as p-anisaldehyde
The effect of the withdrawing ability of –CF3 groups in a large and flexible bidentate ligand has been evaluated by monitoring the course of solid-state dehydrochlorination reactions. We demonstrate that the coordination bond formation does not occur by mechanochemical means from a second coordination sphere adduct. Quantum mechanical calculations have shown that frontier molecular orbital energy and
