In 1967 Pederson reported the synthesis of macrocyclic crown ethers and their ability to
selectively bind alkali and alkaline earth ions, 1, 2 and since then supramolecular …

Abstract Metal-organic frameworks (MOFs), consisting of metal ions or clusters coordinated

In 1990, Fujita and co-workers described the first example of a rationally designed
metallacycle, the molecular square [{Pd (en)(μ-4, 4′-bipy)} 4](NO3) 8, prepared by self …

This Perspective summarises the chemistry of the pyrazole ring, and reviews the metal
coordination modes adopted by 1H-pyrazoles and their anions. Pyrazolide anions are …

We describe herein the characterization of three novel supramolecular anion-encapsulating
assemblies, where neutral covalently-bound host units converge around the anionic guests …

Hydrothermal reactions of 1, 2, 4-triazole with the appropriate copper salt have provided
eight structurally unique members of the Cu/triazolate/X system, with X= F-, Cl-, Br-, I-, OH …

A spin density functional (SDFT) study of carboxylate-bridged and diazenido-bridged
