• A solvothermal synthesis method using Co(NO 3 ) 2 ·6H 2 O, thiophene dicarboxylic acid (H 2 tpdc), and 1,4-bis(1-imidazoly) benzene (bib) as raw materials was reported to control the growth of coordination polymers by adjusting the solvent polarity. Then, three coordination polymers with the same conformational unit and ligand and different dimensions were synthesized under three different solvent polarities. In addition, the electrochemical hydrogen evolution reaction (HER) properties of compounds 2D and 3D after high temperature pyrolysis were also investigated. The results show that compound 2D showed a better HER performance than compound 3D . We explained the reasons that compound 2D showed a better HER performance through detailed characterization. A slight change of the solvent plays an important role in the synthesis process, and a small change in the crystal structure can also lead to a large difference in performance.
