Presented here are a series of indium-organic frameworks synthesized by the self-assembly of In3+ salts and 1,1'-ferrocenedicarboxylic acid (H2FcDCA). Nitrogen-containing organic additives played various roles in the diversity of the structures. These compounds exhibit diverse frameworks with rich supramolecular interactions, which show good photoelectronic and redox activity together with active FcDCA ligands. Moreover, the indium-based MIL-53 analogue exhibited permanent porosity and gas separation.
