Cover Story: Growing crystals in a gel matrix is possible to induce a huge variety of crystal shapes but also deep morphological and structural modifications, including disordered intergrowth crystals, macro- and micromorphology alterations, and gel inclusion phenomena. Moreover, thanks to their versatility, gel diffusion techniques represent a powerful tool to affect the overall kinetic process and, thus, the phase equilibrium composition in multicomponent systems, like the well-known, hybrid functional materials “coordination polymers (CPs)”. The history of crystal growth via a gel method of a CP system based on a cadmium salt and a bipyridyl ligand is reported, including a fascinating in situ observation of the growth process.
