Реферат: Cluster complexes are defined by the presence of covalent bonds between metal atoms. Well-known octahedral cluster complexes have the formula [{M6X8}X6]n-, where M is a metal atom, X is a ligand, and n is a charge. They represent an octahedron of 6 metal atoms, surrounded by 14 ligands. These include eight inner sphere (μ3-) ligands and six outer ligands. Such cluster complexes are frequently reported in the literature because of their potential as agents in photodynamic therapy1. There are also heterometallic examples of compounds based on molybdenum combined with other transition metals such as osmium and rhenium2,3. Heterometallic cluster complexes are promising for the creation of materials with specific functionalities, since changes in the composition of the cluster core can modify the redox and spectroscopic properties of the compounds.3. However, no examples of heterometallic cluster complexes involving 3d-row transition metals have yet been reported in the existing literature. This research presents a synthesis method for a new class of compounds – tungsten-iron bromide cluster complexes with {FeW5} core. In addition, in the work presents crystal structures of compounds obtained under different conditions, evaluates their stability and reactivity with different solvents, and discusses the nature of the bonds in the heterometallic cluster complex based on the results obtained.
