Porous Zirconium Metal-Organic Framework Constructed from 2D → 3D Interpénétration Based on a 3,6-Connected kgd Net.

A new porous zirconium metal--organic frame work (Zr MOF), Zr6 (μ3 - 0)4(/irOH)4(OH)6(H2O)6(BTB)2.6DMFH6O (1; H3BTB = 5'- (4-carboxyphenyl) [1,1' :3' 1"-terphenyl] -4,4"-dicarboxylic acid), based on Zr6 clusters and tricarboxylate ligands has been constructed and characterized. The Zr6 dusters were linked by BTB ligands to generate a 2D network of kgd topology. The interpénétrations among the 2D networks gave rise to a 3D porous framework, which represents the first Zr MOF constructed from 2D → 3D interpénétration. The gas uptake and catalytic properties for 1 have also been studied. [ABSTRACT FROM AUTHOR]
