A two‐dimensional ZnII coordination polymer constructed from benzene‐1,2,3‐tricarboxylic acid and N,N′‐bis[(pyridin‐4‐yl)methylidene]hydrazine

The hydrothermal synthesis of the novel complex poly[aqua(μ₄‐benzene‐1,2,3‐tricarboxylato)[μ₂‐4,4′‐(hydrazine‐1,2‐diylidenedimethanylylidene)dipyridine](μ₃‐hydroxido)dizinc(II)], [Zn(C₉H₃O₆)(OH)(C₁₂H₁₀N₄)(H₂O)]_n, is described. The benzene‐1,2,3‐tricarboxylate ligand connects neighbouring Zn₄(OH)₂ secondary building units (SBUs) producing an infinite one‐dimensional chain. Adjacent one‐dimensional chains are connected by the N,N′‐bis[(pyridin‐4‐yl)methylidene]hydrazine ligand, forming a two‐dimensional layered structure. Adjacent layers are stacked to generate a three‐dimensional supramolecular architecture via O—H...O hydrogen‐bond interactions. The thermal stability of this complex is described and the complex also appears to have potential for application as a luminescent material.
