Resumo

It is well-known that crystalline materials obtain their fundamental physical properties from the molecular arrangement within the solid, and altering the placement and or interactions between these molecules can impact the properties of the particular solid. Solid state chemistry looks at an attempt to alter the chemical and physical solid-state properties of APIs through many different strategies as the formation of salts, polymorphs, hydrates, solvates, and cocrystals. The final aim of this work is to study the chemical and physical propriety of new crystal structures. The work consists of three parts. The first is the cocrystallization of α,ω-alkanedicarboxylics acids with pirimidine. Single-crystal X-ray diffraction analysis of this adduct have been carried out at RT, 150 and 200 K. The cocrystals show an alteration of their melting point similar to pure acids. The two significant deviations are for the cocrystals with succinico and glutarico acids. The second object of work is the structure determination of β polymorph undecandioic acids. In literature is known the other polymorph α. We observed that the thermodynamic relation for this dimorphics system is monotropic. In the third part we synthesized and analyzed the stability of four new salts of serine and oxalic acid. This project highlights the advantage of the solid state synthesis.
