Coordination Chemistry of Ruthenium

Ruthenium is one of the rare elements that belongs to the platinum group metals. Ruthenium is very effective hardener for platinum and palladium. Well studied coordination and organometallic chemistry of ruthenium results in a various varieties of compounds. There are various features of ruthenium such as oxidation states, coordination numbers and geometries. Ruthenium compounds have various applications and also have low toxicity and they are ideal for the catalytic synthesis of drugs. The field of ruthenium chemistry is very broad and is extremely diverse in the field of catalysis and medicinal chemistry. This review article shows a classical general chemistry of ruthenium compounds.
