Syntheses of Formato-, Acetato-, Benzoato-, and Chlorosubstituted Acetatoruthenium Complexes, and Their Properties

Abstract

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.

Synthesis, Properties, and Structural Characterization of Bromo‐ and Iodotetracarboxylatodiruthenium(II,III) Compounds

“…In the iodo derivatives a strong shift of the π(RuO,Ru 2 ) Ǟ π*(Ru 2 ) transition is also induced, thereby producing solvatochromism for these complexes. [9,11,31] IR spectra were recorded as KBr discs on a Nicolet Magna-FTIR 550 spectrophotometer. Elemental analysis of C and H were performed by the Microanalytical Service of the Complutense University of Madrid.…”

Synthesis, Crystal Structure, and Magnetic Properties of Amidate and Carboxylate Dimers of Ruthenium

“…The precursors [Ru 2 X(µ-O 2 CMe) 4 ] (X = Cl, Br, I) were synthesized according to a published procedure [32][33][34].…”

Polymeric, Molecular, and Cation/Anion Arrangements in Chloro‐, Bromo‐, and Iododiruthenium(II,III) Carboxylate Compounds

“…[21,22] Few bromo and iodo derivatives have been reported, [23,24] and the influence of the halogen axial ligand on the structure has not been studied. [Ru 2 Br(µ-O 2 CH) 4 ] is the sole example of this kind of compounds whose crystal structure has been reported.…”
