Modulator Driven Formation of a Very Complex Self-Catenated Zinc Metal–Organic Framework
Solvothermal reaction of <i>N</i>,<i>N</i>'-bis-(5-isophthalic acid)-naphthalenediimide (H<sub>4</sub>BINDI) with zinc-(II) nitrate hexahydrate in dimethylformamide (DMF) in the presence of trifluoroacetic acid as a modulator gives rise to a self-catenated Metal-organic framework (MOF) termed BINDI-ZnSC of unprecedented topological complexity. Using the "all node" method, the topology is assigned as a six-nodal net with point symbol {4.10<sup>2</sup>}<sub>2</sub>{4.12<sup>2</sup>}-{4.6.8}-{4<sup>2</sup>.6.8.10<sup>6</sup>}-{6.10<sup>2</sup>}. In contrast to interpenetrated and other self-catenated MOFs that often exhibit limited pore volume, BINDI-ZnSC exhibits a total of 3730 Å<sup>3</sup> (62.5% of the unit cell) of solvent-filled channels per unit cell, suggesting that the material is potentially capable of encapsulating not only single molecules but also molecular clusters of some small molecules.
