In this work, we designed and synthesized a novel porphyrin-based ligand 5,10,15,20-tetrakis­(4,4′-dipyridylaminophenylene)­porphyrin (TDPAP, H<sub>2</sub>L) by the introduction of four peripheral 4,4′-dipyridylamine moieties to a porphyrin platform. Starting from this novel ligand, the protonated form of the ligand H<sub>4</sub>LCl<sub>2</sub>·2CH<sub>3</sub>OH­·2H<sub>2</sub>O (<b>1</b>) and four coordination polymers [Mn­(III)­Mn­(II)­LCl<sub>3</sub>­(DMF)]<sub><i>n</i></sub> (<b>2</b>), [Cu<sub>4</sub>L­(CH<sub>3</sub>COO)<sub>5</sub>­(HCOO)­(CH<sub>3</sub>COOH)­(H<sub>2</sub>O)<sub>3</sub>]<sub><i>n</i></sub>­·<i>n</i>CH<sub>3</sub>COOH­·<i>n</i>H<sub>2</sub>O (<b>3</b>), [Zn<sub>3</sub>L­(CH<sub>3</sub>COO)<sub>4</sub>]<sub><i>n</i></sub> (<b>4</b>), and [Cd<sub>2</sub>H<sub>2</sub>L­(CH<sub>3</sub>COO)<sub>4</sub>]<sub><i>n</i></sub>­·<i>n</i>DMF­·<i>n</i>CH<sub>3</sub>COOH­·2<i>n</i>H<sub>2</sub>O (<b>5</b>) were synthesized. Single crystal X-ray diffraction analyses revealed that a rich structural diversity was observed for these compounds due to the coordination of the multiple peripheral pyridines as well as the porphyrin core. <b>1</b> displays a hydrogen bonded one-dimensional (1D) structure composed of [(H<sub>2</sub>O)<sub>2</sub>Cl<sub>2</sub>]<sup>2–</sup> moieties. Complex <b>2</b> shows interpenetrated two-dimensional (2D) coordination networks, which are further linked by π···π stacking interactions to afford a three-dimensional (3D) structure. <b>3</b> shows a 2D sheet composed of 50- and 70-membered metallomacrocycles. In complex <b>4</b>, 1D zigzag coordination chains were generated and further linked to form a 2D structure. Complex <b>5</b> has a stairlike 2D structure formed by the linkage of 1D coordination chains through the bridging of binuclear [Cd<sub>2</sub>(CO<sub>2</sub>)<sub>4</sub>] subunits. In these compounds, TDPAP shows a unique coordination behavior. It may bind 4–7 metal centers, and it demonstrates conformational flexibility and the ability to form intermolecular hydrogen bonds and π···π interactions, which contribute to the formation of novel supramolecular structures. On the basis of the novel structures, the solid state emissions of the compounds were also investigated.
