WebFeb 17, 2024 · We used perrhenate anions as a model. It is known that these two anions are very similar in geometry as well as chemical properties [ 32, 33, 34 ]. 2. Results and Discussions 2.1. Synthesis and X-ray Phase Analysis We started our study by investigating the reaction of pyridine with cyanuric chloride 1 ( Scheme 1 ). WebSupramolecular recognition of perrhenate is a challenging task due to therelatively large size and low charge density of this anion. In this work, we design and synthesize a family of helix-like synthetic receptors that can bind perrhenate by forming hydrogen bonds with all four oxygen atoms of the anion.
