Abstract
Calixpyrroles bind anions efficiently and can be transformed into transition-metal complexes only under forcing conditions. Reducing the macrocycle creates a ligand that easily forms classical Werner complexes with Cu, Ni, and Pd ions. The metal complexes present an array of four directed H bonds, which specifically bind the counterions. [on SciFinder(R)]
