Abstract
In this study, we present a convenient and accessible synthesis of [M6X8(OCH3)6]2− clusters from [M6X8X6]2− (M = Mo, W; X = Br, I) using methanol and sodium hydroxide, without the use of absolute solvents or sodium methylate. The substitution of terminal methylate ligands in the clusters by pyrazolate ligands was conducted using a reaction in the melt of the organic ligand. The formation of anionic [M6X8(pz)6]2− (pz = pyrazolate) complexes was confirmed by both single crystal X-ray diffraction analysis and 1H NMR spectroscopy in solution. The complexes exhibited broadband emission in solid state with emission maxima ranging from 600 to 700 nm (depending on the cluster core) with quantum yields of approximately 7 %.
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.
