Popis: Lithium salt of binuclear ruthenium nitride complex Li3[Ru2NCl8 · 2H2O] has been synthesized. Structure of the complex was studied by X-ray diffraction. Triclinic crystals, space group P $$\bar {1},$$ a = 7.4044 A, b = 8.1818 A, c = 8.7123 A, α = 117.970°, β = 115.139°, γ = 90.014°, V = 408.65 A3, Z = 1, ρcalcd = 2.654 g/cm3. The complex is thermally stable, it dimerizes in acid medium to give tetranuclear cluster $${\text{R}}{{{\text{u}}}_{{\text{4}}}}{{{\text{N}}}_{{\text{2}}}}{\text{O}}_{{\text{5}}}^{ + }$$ , an active catalyst of four-electron oxidation of water to form O2. Catalyst efficiency in the reaction of water oxidation (TON) reaches 356 over 1 h.
