Molecular hydride carbonyl clusters and nanoclusters
This minireview outlines the actual status of the chemistry of hydride metal carbonyl clusters (MCCs) by means of pertinent examples, without being comprehensive. After a brief introduction to the topic, the major synthetic routes for the introduction of hydride ligands in MCCs are described, with particular focus on the different typologies of reagents that can be employed. The structures of hydride MCCs and the different coordination modes of hydride ligands are, then presented, based on single-crystal X-ray and neutron diffraction data available. Some general considerations on 1H NMR studies of hydride MCCs are described, including fluxionality and the problems of detecting hydrides in larger MCCs. Moreover, electrochemical studies of hydride MCCs are summarized, focusing on electrochemistry as an indirect tool for determining the hydride nature of large MCCs, and tuning the redox potentials of MCCs by protonation/deprotonation reactions. Applications of hydride MCCs in catalysis and electrocatalysis are only briefly described at the end of this minireview, since this topic has been recently reviewed.
期刊介绍:
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
