Metal–organic materials (MOMs) and coordination polymers (CPs) are among the most prolific research areas of inorganic coordination chemistry and crystal engineering in the last 15 years [1,2]. The research interest to these compounds is increasing rapidly due to their potential applications such as synthetic sponges with adsorption properties, luminescence, magnetism, catalysis, redox activity, and astonishing architectures. Due to inherent modulation, different CPs and MOMs topologies can be obtained by combining metal ions (node) with organic molecules (linker). Ligands used in construction of CPs have to mediate metal ions. This usually requires multidentate ligands, with two or more electron-donor atoms. The combination of pyridyl and carboxyl groups in a single “bridge”-type ligand results in highly interconnected networks and gives limitless possibilities for increase network stability and porosity [3,4]. The project was aimed on directed design, and synthesis of new coordination compounds with predicted composition, architectural topology and specific properties. The objectives of the project were:
The implementation of these objectives was carried out on coordination compounds containing a number of transition 3d- metals, and representatives of the main classes of the accessible organic linkers including dicarboxylic acids, aromatic amines, oximes and their derivatives, as well as the complementary organic molecules with the bridge functions as auxiliary ligands. |
