Popis: | The synthesis of binuclear ruthenium(IV) oxochloride complex and reaction of the latter with LiCl in a 2.5 M HCl solution have been carried out. The reaction of Ru(IV) binding in solution leads to the formation of a new cluster compound Li8Ru2OCl14 (I) whose molecular structure has been determined by X-ray diffraction. The crystals are tetragonal, space group $$I\bar 42m$$ , a = 7.08 A, c = 17.00 A, V = 852.18 A3, Z = 2. Supramolecular structural self-organization of I includes the formation of layers parallel to the xy plane. The high thermal stability of complex I and retention of its dinuclear structure in an acidic environment have been shown by thermal analysis and IR and electronic spectroscopy. It has been found that cluster I is an efficient catalyst for water oxidation in artificial photosynthesis. |
