The complex has octahedral geometry. [1] The synthesis of this complex was reported for the first time in 1980, it was prepared by mixing ruthenium trichloride and terpyridine in ethanol, heating the mixture to reflux conditions [2] A later synthetic protocol uses a similar approach by heating ruthenium trichloride with a DMF solution of ...
(Terpyridine)ruthenium trichloride is a representative complex of terpyridine. Terpyridine is a tridentate ligand that binds metals at three meridional sites giving two adjacent 5-membered MN 2 C 2 chelate rings. [6] Terpyridine forms complexes with most transition metal ion as do other polypyridine compounds, such as 2,2'-bipyridine and 1,10 ...
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.
Ruthenium trichloride. The highest known ruthenium halide is the hexafluoride, a dark brown solid that melts at 54 °C.It hydrolyzes violently upon contact with water and easily disproportionates to form a mixture of lower ruthenium fluorides, releasing fluorine gas.

A number of ruthenium-aqua complexes catalyze the oxidation of water. Most catalysts feature bipyridine and terpyridine ligands. [3] [4] [2] Catalysts containing pyridine-2-carboxylate exhibit rates (300 s −1) comparable to that of photosystem II. [5] [6] Work in this area has ushered in many new polypyridyl ligands. [7] [8]
Ruthenium is a component of mixed-metal oxide (MMO) anodes used for cathodic protection of underground and submerged structures, and for electrolytic cells for such processes as generating chlorine from salt water. [64] The fluorescence of some ruthenium complexes is quenched by oxygen, finding use in optode sensors for oxygen. [65]
The noteworthy property of ruthenium complexes, chlorides and otherwise, is the existence of more than one oxidation state, several of which are kinetically inert. All second and third-row transition metals form exclusively low spin complexes, whereas ruthenium is special in the stability of adjacent oxidation states, especially Ru(II), Ru(III ...
