Study Notes
Coordination Compounds Overview
- Coordination compounds consist of transition metals bonded to anions or neutral molecules via shared electrons.
- They serve as a fundamental aspect of modern inorganic and bio-inorganic chemistry.
Importance of Coordination Compounds
- Play crucial roles in biological systems:
- Chlorophyll: contains magnesium as a central metal.
- Hemoglobin: incorporates iron, vital for oxygen transport in blood.
- Vitamin B12: includes cobalt, critical for nerve function and red blood cell production.
- Applications extend to various industries:
- Utilized in metallurgical processes to extract and manipulate metals.
- Serve as industrial catalysts to enhance chemical reactions.
- Function as analytical reagents in chemical analysis.
Alfred Werner's Contributions
- Alfred Werner (1866-1919): Swiss chemist recognized as a pioneer in coordination chemistry.
- Developed foundational theories regarding coordination compound structures.
- Introduced two key concepts:
- Primary Valence: Indicates the number of ions bound to a metal.
- Secondary Valence: Refers to the number of coordinating groups attached to the central atom.
- Conducted experiments with cobalt(III) chloride and ammonia, resulting in the discovery that some chloride ions precipitate out as AgCl in reaction with silver nitrate, while others remain dissolved.
