Ruthenium(II) Chloride
Ruthenium(II) chloride is an inorganic compound, a metal salt of ruthenium and hydrochloric acid with the formula . Synthesis *Reaction of chlorine and ruthenium at 250 °C: :: *Reaction of ruthenium trichloride with hydrogen in ethanol in presence of platinum black and hydrogen chloride: :: Physical properties Ruthenium(II) chloride forms brown crystals. Ruthenium(II) chloride is poorly soluble in cold water, but is soluble in ethanol. Chemical properties Ruthenium(II) chloride can form complexes with aromatic hydrocarbon Aromatic compounds, also known as "mono- and polycyclic aromatic hydrocarbons", are organic compounds containing one or more aromatic rings. The parent member of aromatic compounds is benzene. The word "aromatic" originates from the past grouping ...s. The compound can be reduced to elemental ruthenium by hydrogen.

Ruthenium(III) Chloride
Ruthenium(III) chloride is the chemical compound with the formula RuCl3. "Ruthenium(III) chloride" more commonly refers to the hydrate RuCl3·''x''H2O. Both the anhydrous and hydrated species are dark brown or black solids. The hydrate, with a varying proportion of water of crystallization, often approximating to a trihydrate, is a commonly used starting material in ruthenium chemistry. Preparation and properties Anhydrous ruthenium(III) chloride is usually prepared by heating powdered ruthenium metal with chlorine. In the original synthesis, the chlorination was conducted in the presence of carbon monoxide, the product being carried by the gas stream and crystallising upon cooling. Two allotropes of RuCl3 are known. The black α-form adopts the CrCl3-type structure with long Ru-Ru contacts of 346 pm. This allotrope has honeycomb layers of Ru3+ which are surrounded with an octahedral cage of Cl− anions. The ruthenium cations are magnetic residing in a low-spin J~1/2 ground st ...
