Abstract A coordination polymer constructed from the ligand 2, 2′‐bipyridine‐5, 5′‐carboxylate (Bpydc) with hybrid functional groups and the co‐ligand SO 4 2– was synthesized and structurally characterized by single‐crystal X‐ray diffraction. It shows an intriguing structure of parallel infinite Mn–SO 4 double chains resulting from the coordination of SO 4 2– groups to central Mn II atoms. Further linkage of the Bpydc ligands with the Mn–SO 4 double chains gave rise to a three‐dimensional pillar‐layer framework, in which the Mn–SO 4 double chains act as pillars and the Bpydc ligands form the layers. Two types of hydrogen bonds are observed between the SO 4 2– and carboxylate groups. The assembly of the Bpydc ligand and the SO 4 2– co‐ligand with central Mn II atoms results in a binodal (3, 5)‐connected network with a rare 3, 5T1 topology, confirming the feasibility of this strategy in constructing novel architectures. The formation of the dense pillar‐layer framework sustained by Mn‐SO 4 double chains and hydrogen bonds enhances the stability of this coordination polymer and results in a high thermal stability up to 400°C.
