There are several ruthenium chlorides: Ruthenium(II) chloride, a brown salt; Ruthenium(III) chloride, a black salt and the most common ruthenium chloride;
"Ruthenium(III) chloride" more commonly refers to the hydrate RuCl 3 ·xH 2 O. 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.
Ruthenium(II) chloride is an inorganic compound, a metal salt of ruthenium and hydrochloric acid with the formula RuCl 2. [1] [2] Synthesis. Reaction of chlorine and ...
Tris(bipyridine)ruthenium(II) chloride Grubbs' catalyst, which earned a Nobel Prize for its inventor, is used in alkene metathesis reactions. Ruthenium forms a variety of coordination complexes. Examples are the many pentaammine derivatives [Ru(NH 3 ) 5 L] n+ that often exist for both Ru(II) and Ru(III).

The most important reagents for the introduction of ruthenium are ruthenium(III) chloride and triruthenium dodecacarbonyl. In its organometallic compounds, ruthenium is known to adopt oxidation states from -2 ([Ru(CO) 4] 2−) to +6 ([RuN(Me)4] −). Most common are those in the 2+ oxidation state, as illustrated below.
Tris(bipyridine)ruthenium(II) chloride is the chloride salt coordination complex with the formula [Ru(bpy) 3]Cl 2.This polypyridine complex is a red crystalline salt obtained as the hexahydrate, although all of the properties of interest are in the cation [Ru(bpy) 3] 2+, which has received much attention because of its distinctive optical properties.
(Terpyridine)ruthenium trichloride is the coordination complex with the formula RuCl 3 (terpy), where terpy is terpyridine. It is a brown paramagnetic solid that is a precursor to other complexes of ruthenium , mainly by substitution of the chloride ligands.
