Chalcones, α, β-unsaturated ketones, being the by-products of the condensation reactions between acetophenones and aromatic aldehydes widely found their applications in biological and pharmacological fields. Simplicity in structures and the least toxicity make the chalcones to be explored for other diverse applications, and one such prevailing these days is their exploitation as corrosion inhibitors. Corrosion inhibitors, the chemical compounds in corrosive environments reduce the rate of electrochemical degradation of metals and alloys. This review article is a comprehensive overview of diverse coordination modes opted by chalcones in the presence of different metals, highlighting the role of various functional groups in governing coordination behavior. The impacts of these coordination complexes over corrosion-inhibiting properties have been discussed, shedding light on the mechanisms underlying their anti-corrosive properties. Furthermore, the recent advancements in various synthesis modes emphasizing their potential for corrosion inhibition have been reviewed. The structure–activity relationships have been discussed to gain insights into the key fundamentals influencing the effectiveness of chalcones and their derivatives in corrosion safeguarding. Conclusively, the review presents the current state of knowledge regarding the coordination chemistry of chalcones and their anti-corrosive applications. The insights provided here aim to guide future research efforts in designing novel chalcone-based corrosion moieties with enhanced effectiveness and environmental sustainability.
