Sažetak
Molecular crystals have for a long been considered as brittle, inelastic, and incapable of enduring application of even relatively insignificant mechanical stress without losing their integrity. But recently, there has been a number of examples where crystals can respond to external mechanical stimuli. It was shown that macroscopic mechanical behavior of crystalline material is mostly determined by the strength and geometry of supramolecular interactions as well as their mutual arrangement in a 3-D architecture. Recently, we have for the first time reported on a class of coordination polymers of cadmium(II) with halopyrazine ligands that display tunable elastic responses to applied mechanical force. To refine our understanding of this unusual phenomenon of metal-organic crystalline materials, here we report on a similar class of coordination polymers of cadmium(II) with pyrazine ligands bearing amide functionalities, capable of forming desired supramolecular topologies that allow us correlation of slight structural changes with a mechanical response. The crystals have also shown excellent elastic response to applied external stimuli that was quantified and structural changes in bent crystals were mapped.
