Complexes with the general formula of [Ru2(RCOO)4X], where R=H, X=Cl, or Br; R=Me, X=Cl, Br, I, SCN, NO3, or MeCOO; R=ph, X=Cl, or Br, were prepared. The magnetic properties, conductivities, polarographic behavior, and infrared spectra of these complexes were investigated. All the complexes show magnetic moments of 2.84–2.96 B.M., and their susceptibilities, at from about 300 to 100°K, can be fitted to the Curie-Weiss law with negative values of the Weiss constant (θ=−30–−60°K). These complexes seem to be isostructural. Monochloroacetato-, and trichloroacetatoruthenium complexes ([Ru2(CH2ClCOO)4Cl]·2H2O and [Ru(OH)(CCl3COO)2(H2O)]) were also prepared.
