Bismuth Coordination Polymers with Fluorinated Linkers: Aqueous Stability, Bivolatility, and Adsorptive Behavior.

ABSTRACT: Bismuth metal-organic frameworks and coordination polymers (CP) are challenging to synthesize, given the poor solubility of bismuth precursors and asymmetric and labile ligation of Bi³⁺ due to its intrinsic lone pair. Here, we synthesize and structurally characterize three Bi³⁺-CPs, exploiting a tetrafluoroterephtalate (F₄BDC) linker to determine the effect of high acidity on these synthesis and coordination challenges. Single-crystal X-ray diffraction characterization showed that pi-pi stacking of linkers directs framework arrangement and generally deters open porosity in the three structures, respectively featuring Bi chains (Bi _chain -F ₄ BDC), Bi dimers (Bi ₂ -F
