Ruthenium complexes typically adopt oxidation states II, III, and IV. The geometry assumed by most ruthenium complexes is hexacoordinate, and octahedral, which differs from the square planar molecular geometry typical for platinum (II). The presence of six ligands allows for tuning of the complexes' electronic and steric properties.

Ruthenium je za normálních podmínek velice nereaktivní kov. Jelikož se v Beketovově řadě kovů nachází vpravo (je ušlechtilý kov), nereaguje s mnoha kyselinami, jako je kyselina chlorovodíková a podobně. Nereaguje však ani s kyselinami, které reagují i s ušlechtilými kovy, tj.: kyselina sírová či kyselina dusičná.V lučavce královské se nerozpouští ani za tepla.
