Preparation and characterization of two supramolecular complexes with 5-amino-2,4,6-triiodoisophthalic acid under N-donor auxiliary ligand intervention

► Two supramolecular complexes with 5-amino-2,4,6-triiodoisophthalic acid have been synthesized. ► Distinct extended 3D network architectures are constructed with the help of weak interactions. ► Halogen bonds play important roles in the supramolecular assembly. ► Solid state fluorescent properties have been studied.
