Naphthyridine-imidazole hybrid ligands for the construction of multinuclear architecture

► Naphthyridine-imidazole hybrid ligands are utilized for the synthesis of multinuclear compounds. ► Dinuclear, cyclic tetranuclear and polymeric chain compounds are accessed via the self-assembly of 'Rh(COD)' with composite N-donor ligands. ► A subtle alteration in the ligand framework affords self-assembled structures of varied nuclearity and diverse topology.
