Sažetak
During the last several decades we have been witnessing a paradigm shift in perception of crystalline matter. For long crystals have been regarded as still, brittle and stationary objects, but recently there has been a growing number of examples where crystals were described to display a variety of mobility. They were found to jump, rotate, flex, fragment or explode as a result of their exposure to the stimuli such as irradiation or heat. On the other hand, mechanically induced crystal flexibility has only recently been observed on a number of molecular organic crystals, but the field subsequently started to develop explosively. A short while ago, we were happy to deliver the first report on crystalline coordination polymers, a series of cadmium(II) compounds, that display exceptional elastic flexibility. Besides, we have shown that the extent of elasticity could be changed by subtle modifications in the geometry of intermolecular interactions and their importance in the crystal packing. Here, several similar crystalline 1-D coordination polymers will be presented, displaying different nature (plasticity vs. elasticity) and the extent of mechanically induced flexibility as a result of an alterations, and consequently, their impact on supramolecular connectivity and the arrangement of metal- containing building units in the crystal.
