Crystal structures are determined by X-ray diffraction techniques (like single crystal or powder diffraction) but they can also be predicted or simulated through theoretical calculations, with periodic boundary conditions. The goal of this research is unveiling the molecular and supramolecular bonding mechanisms that rule the build up of these structures, and understanding the atomic/molecular origin of crystalline properties. The investigated compounds are organic or organometallic molecules or coordination polymers. The latter are synthesized by solvothermal methods and structurally characterized by diffraction methods. The materials functionalities which are investigated are linked to optoelectronic, magnetic, adsorption properties.
