The European Colloquium on Inorganic Reaction Mechanisms is a biennial event gathering the chemical community interested in mechanistic studies involving inorganic compounds. Topics covered by the 2024 edition, held in the beautiful city of Toulouse, include coordination, bioinorganic and organometallic chemistry, physico-chemical methods, kinetics, catalysis, energy and surface science, and theoretical modeling. The program will comprise invited lectures, oral communications and posters over 4 days in a single session schedule for stimulating scientific discussions. We look forward to your contributions and to welcoming you in Toulouse in September 2024.
