Introduction to Organometallic Chemistry: Bonding and the 18-Electron Rule

Organometallic chemistry bridges the gap between organic and inorganic chemistry, serving as the backbone for modern industrial catalysis and synthesis. Understanding how transition metals interact with organic ligands is essential for anyone pursuing academic or professional paths in chemical sciences. This text-based course guides you through the core concepts of organometallic chemistry, starting with basic definitions and coordination chemistry, before moving into bonding models and electron counting. You will develop the confidence to analyze complex metal-carbon structures and predict their stability. What you'll learn: Understand the fundamental classifications of organometallic compounds and coordination complexes; Master the 18-electron rule to predict the stability of transition metal complexes; Analyze metal-ligand bonding, including sigma-bonding, pi-backbonding, and hapticity; Explore key ligand types, such as carbonyls, phosphines, and hydrides, and their chemical behavior; Practice analyzing reaction pathways and fundamental organometallic transformations; Learn how these principles apply to modern homogeneous catalysis and green chemistry. The course begins with essential terminology and foundational bonding theories, progressing systematically to electron counting methods and complex structures. Through clear written explanations and step-by-step structural breakdowns, you will build a strong theoretical foundation. Designed for undergraduate chemistry students, chemical engineering majors, and self-directed learners seeking a solid introduction to organometallic systems, this course requires no advanced inorganic chemistry prerequisites.
