The design and synthesis of complicated multidentate ligands for the creation of polynuclear complexes with predetermined functions or structures occupy an increasingly prominent place in coordination chemistry. This approach has become common practice in such wide contexts as bioinorganic modelling, photochemistry, or molecular devices. Various ligands with distinct geometries and coordination modes have been designed and the bis-β- diketones have been proven to be qualified to construct the new supramolecular architectures. The opportunity to control the shape, flexibility and functionality allows bis-β-diketones to be excellent building units for the creation of cyclic structures as well as multiple-stranded helicates, MOF’s, linear molecular platforms and metallamacrocycles. Metallosupramolecules have generated a great deal of interest due to their various interesting properties, among which the catalytic, magnetic and optical activity must be mentioned. In this work, new bis-β-diketone ligands based on organosilicon derivatives of dibenzoylmethane were synthesized and their interaction with transition metal ions was studied
