Abstract

The assembly of metal–organic frameworks (MOFs) with metal ions and organic ligands is currently attracting considerable attention in crystal engineering and materials science due to their intriguing architectures and potential applications. A new three‐dimensional MOF, namely poly[[diaqua(μ8‐para‐terphenyl‐3,3′,5,5′‐tetracarboxylato)dizinc(II)] dimethylformamide disolvate monohydrate], {[Zn2(C22H10O8)(H2O)2]·2C3H7NO·H2O}n, was synthesized by the self‐assembly of Zn(NO3)2·6H2O and para‐terphenyl‐3,3′,5,5′‐tetracarboxylic acid (H4TPTC) under solvothermal conditions. The compound was structurally characterized by FT–IR spectroscopy, elemental analysis and single‐crystal X‐ray diffraction analysis. Each ZnII ion is located in a square‐pyramidal geometry and is coordinated by four carboxylate O atoms from four different TPTC4− ligands. Pairs of adjacent equivalent ZnII ions are bridged by four carboxylate groups, forming [Zn2(O2CR)4] (R = terphenyl) paddle‐wheel units. One aqua ligand binds to each ZnII centre along the paddle‐wheel axis. Each [Zn2(O2CR)4] paddle wheel is further linked to four terphenyl connectors to give a three‐dimensional framework with NBO‐type topology. The thermal stability and solid‐state photoluminescence properties of the title compound have also been investigated. A three‐dimensional NBO‐type topological metal–organic framework (MOF) formed from zinc(II) and para‐terphenyl‐3,3′,5,5′‐tetracarboxylate was synthesized by solvothermal reaction.
