In recent years, N‐heterocyclic carboxylate ligands have attracted much interest in the preparation of new coordination polymers since they contain N‐atom donors, as well as O‐atom donors, and have a rich variety of coordination modes which can lead to polymers with intriguing structures and interesting properties. A new two‐dimensional coordination polymer, namely poly[[μ 3 ‐2,2′‐(1,2‐phenylene)bis(4‐carboxy‐1 H ‐imidazole‐5‐carboxylato)‐κ 6 O 4 , N 3 , N 3′ , O 4′ : O 5 : O 5′ ]manganese(II)], [Mn(C 16 H 8 N 4 O 8 )] n or [Mn(H 4 Phbidc)] n , has been synthesized by the reaction of Mn(OAc) 2 ·4H 2 O (OAc is acetate) with 2,2′‐(1,2‐phenylene)bis(1 H ‐imidazole‐4,5‐dicarboxylic acid) (H 6 Phbidc) under solvothermal conditions. In the polymer, each Mn II ion is six‐coordinated by two N atoms from one H 4 Phbidc 2− ligand and by four O atoms from three H 4 Phbidc 2− ligands, forming a significantly distorted octahedral MnN 2 O 4 coordination geometry. The Mn II ions are linked by hexadentate H 4 Phbidc 2− ligands, leading to a two‐dimensional structure parallel to the ac plane. In the crystal, adjacent layers are further connected by N—H…O hydrogen bonds, forming a three‐dimensional structure in the solid state.
