metallacrown
Metallacrowns are a unique class of macrocyclic compounds that consist of metal ions and solely or predominantly heteroatoms in the ring. Classically, metallacrowns contain an () repeat unit in the macrocycle. First discovered by Prof. Vincent L. Pecoraro and Myoung Soo Lah in 1989, metallacrowns are best described as inorganic analogues of crown ethers. To date, over 600 reports of metallacrown research have been published. Metallacrowns with sizes ranging from 12-MC-4 to 60-MC-20 have been synthesized.
In 2013, the project "Metallacrowns - Metallacrowns-based innovative materials and supramolecula devices" has been funded by the European Union - Research Executive Agency as a Marie Curie IRSES International Research Staff Exchange Scheme. This mobility project involves researchers from the Universities of Parma, Wroclaw, Paris-Sud, Kiev, and Michigan, and the CNRS in Orleans. This project has been funded by the European Community's Seventh Framework Programme (FP7/2007-2013) under grant agreement n° 611488.
==Nomenclature==
Metallacrown nomenclature has been developed to mimic the nomenclature of crown ethers, which are named by the total number of atoms in the ring, followed by “C” for “crown,” and the number of oxygen atoms in the ring. For example, 12-crown-4 or 12-C-4 describes Figure 2a. When naming metallacrowns, a similar format is followed. However, the C becomes “MC” for “metallacrown” and the “MC” is followed by the ring metal, other heteroatom, and the ligand used to make the metallacrown. For example, the metallacrown in Figure 2b is named (), where “shi” is the ligand, salicylhydroxamic acid.〔
