Ruthenium(III) acetate, commonly known as basic ruthenium acetate, [1] describes a family of salts where the cation has the formula [Ru 3 O(O 2 CCH 3) 6 (OH 2) 3] +.A representative derivative is the dihydrate of the tetrafluoroborate salt [Ru 3 O(O 2 CCH 3) 6 (OH 2) 3]BF 4 (H 2 O) 2, which is the source of the data in the table above.

Ruthenium(III) acetylacetonate is a coordination complex with the formula Ru(O 2 C 5 H 7) 3. O 2 C 5 H 7 − is the ligand called acetylacetonate . This compound exists as a dark red solid that is soluble in most organic solvents. [ 3 ]
Ruthenium is a chemical element; it has symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table. Like the other metals of the platinum group, ruthenium is unreactive to most chemicals.
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.
Perruthenate can be considered as the partially reduced derivative of ruthenium tetroxide. It is a much milder oxidising agent than the unionised compound, but still capable of oxidising a number of compounds via its reduction to ruthenate RuO 2− 4 .
Diruthenium tetraacetate chloride is the coordination polymer with the formula {[Ru 2 (O 2 CCH 3) 4]Cl} n. A red brown solid, the compound is obtained by the reduction of ruthenium trichloride in acetic acid. [1] The compound has attracted much academic interest because it features a fractional metal-metal bond order of 2.5. [2]
One of the ruthenium atoms is in a +3 oxidation state, and the other in a +4 oxidation state. In addition to the four ammonia ligands, each ruthenium also has one formate group and there are a total of three chloride ions to balance the charge. In solution, chloride or hydroxide groups displace the formates. [1]
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.
