Mechanically Responsive Crystalline Coordination Polymers with Controllable Elasticity
Crystalline coordination polymers tend to be brittle and inelastic, however, we now describe a family of such compounds that are capable of displaying mechanical elasticity in response to external pressure. The design protocol successfully targets structural features that are critical for producing the desired mechanical output. The elastic crystals all comprise 1‐D cadmium(II) halide polymeric chains with adjacent metal‐centres bridged by two halide ions resulting in the required stacking interactions and short ‘4 Å’ crystallographic axes. These polymeric chains (structural “spines”) are further organized via hydrogen‐ and halogen bonds perpendicular to the direction of the chains. By carefully altering the strength and the geometry of these non‐covalent interactions, we have demonstrated that it is possible to control the extent of elastic bending in crystalline coordination compounds.
