Passage

Coordination compounds play a vital role in our lives. The importance of these compounds can be realised from the fact that life would not have been possible without the existence of chlorophyll in plants and haemoglobin in the blood of the animals. The field of such compounds has expanded very fast in recent years and coordination compounds are playing important roles in analytical chemistry, polymerisation reactions, metallurgy and refining of metals, etc.
