Abstract
The title compound of a lantern-type diruthenium(II,III) complex, [Ru2(2,6-Me2-pf)(O2CMe)3Cl(THF)2]·0.5THF·H2O (2,6-Me2-pf = N,N′-bis(2,6-dimethylphenyl) formamidinate ion), was isolated, and the crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. It crystallizes in the monoclinic space group C2/c with a = 26.178(5)Å, b = 13.567(3)Å, c = 18.796(4)Å, β = 108.168(4)°, V = 6343(2)Å3, Dx = 1.659 g/cm3, and Z = 8. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0294 and 0.0591, respectively, for all 7283 independent reflections. The Ru-Ru distance is 2.2931(5)Å and the axial Ru-Cl and Ru-O (THF) distances are 2.4923(9) and 2.315(2)Å, respectively. The 1H NMR spectrum was measured in CD2Cl2 at 298 K, and the observed signals were assigned for the 2,6-Me2-pf- and MeCO2- ligands.
