Spectrophotometric approach, in vitro antibacterial, anticancer and antioxidant properties of Iridium complexes – A Review

Abstract

Iridium out of the members of group 9 is one of the most important rare elements found in the earth’s crust and usually occurs in an uncombined state or in natural alloys which include osmiridium(Iridium rich) and iridosmine(Osmium rich). Interestingly despite of its low reactivity, iridium can create a variety of compounds with oxidation states ranging from -3 to +9. In addition to the unique electronic configuration, iridium shows low toxicity and a low environmental impact, making it a green element. Attributing to these properties, iridium and its complexes exhibit a wide range of applications including industrial, medicinal and catalysis. Besides this, its compounds are also utilized as anticancer, antibacterial and antioxidant agents in electrical and electrochemical processes as well as in energy production. Owing to the immense range of applications of iridium and its complexes, there is an exigency to create and investigate the methods of iridium analysis which are highly rich in the behavioural properties of handling, sensitivity, versatility and cost effectiveness.
