Molecular tectonics of mixed-ligand metal-organic frameworks: Positional isomeric effect, and structural diversification

This work presents three CdII coordination polymers based on a novel 2-(3-(pyridin-2-yl)-1H-pyrazol-1-yl)acetonitrile (PPAN) and different polycarboxylate isomers (1,3-benzenedicarboxylic acid, 1,3,5-benzenetricarboxylic acid, 1,2,4,5-benzenetetracarboxylic acid), which exhibit distinct 1D layered and 2D network coordination arrays.208
