On the Blue Complexes Formed in Acidic Solutions of Hexaammineruthenium(II)

Abstract

The blue complex formed by reaction of hexaammineruthenium(II) dichloride and hydrochloric acid bas been characterized by analytical, spectroscopic, electrochemical, and chemical methods as a chlorobridged ruthenium(II)–ruthenium(III) dimer, [Ru2(NH3)6Cl4H2O]Cl. With hydrobromic acid the analogous complex [Ru2(NH3)6Br4H2O]Br is formed. Reactions of the complexes with ammonia and hydrohalic acids are reported.

Amphiphilic dendritic copolymers of tert-butyl-glycidylether and glycidol as a nanocontainer for an anticancer ruthenium complex

“…Ru(NH 3 ) 3 Cl 3 was collected on the filter paper, washed several times with methanol and acetone and dried under vacuum. The results obtained from UV and infrared spectroscopy on the obtained material were in accord with those reported in the literature …”

“…Triamminetrichlororuthenium was synthesized using procedures found in the literature . Ruthenium (III) chloride hydrate (4.8 mmol, 1 g) was placed in a round bottom flask and dissolved in 5 mL of water.…”

A Dimeric Complex of Ruthenium: A New Inhibitor of Respiration-driven Calcium Transport in Escherichia coli K12

“…The dimeric, mixed-valence complex of ruthenium, of composition Ru,(NH,),BrS(H20) was prepared by the method of Bottomley & Tong (1971). The precise formulation of the complex is not clear.…”

On the blue complexes of ruthenium. Part II. The structure of fac-trichlorotriammineruthenium(III)

“…In a previous paper we outlined our investigations of the blue species obtained by treating hexaammii~eruthenium (11) with hydrohalic acids (1). We found that the blue complexes were ruthenium(I1)-ruthenium(II1) dimers of empirical formula Ru2X,(NH3),H20 (X = C1, Br), and suggested the dimeric cation contained a single halo-bridge, i.e.…”
