The properties of ruthenium and osmium compounds are often similar. The +2, +3, and +4 states are the most common. The +2, +3, and +4 states are the most common. The most prevalent precursor is ruthenium trichloride , a red solid that is poorly defined chemically but versatile synthetically.
With its similar properties to and lower cost than rhodium, electric contacts are a major use of ruthenium. The ruthenium plate is applied to the electrical contact and electrode base metal by electroplating or sputtering. Osmium is a hard but brittle metal that remains lustrous even at high temperatures. It has a very low compressibility.

Johannes G. Vos (born 1949), also known as Han Vos is Emeritus Professor of Inorganic Chemistry at Dublin City University in Ireland. [1]His early work was on the synthesis, characterisation and physical properties of mononuclear and oligonuclear ruthenium and osmium containing polypyridyl compounds.
The physical properties of the refractory elements vary significantly because they are members of different groups of the periodic table. [ 6 ] [ 7 ] The hardness, high melting and boiling points, and high enthalpies of atomization of these metals arise from the partial occupation of the outer d subshell , allowing the d electrons to ...
A map shows the 132 acres of land that's been annexed for anticipated development of a sixth Microsoft data center, to be called Ruthenium. Osmium, the company's third data center, can be seen to ...
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.
