description Alfred Werner Overview

Alfred Werner was a Swiss chemist whose groundbreaking work established the theory of coordination compounds. His models, detailing how metals bond with surrounding molecules, fundamentally shaped twentieth-century chemistry. He elucidated the geometric arrangement of atoms around central metal ions, earning him the 1913 Nobel Prize. This research is crucial for understanding and developing materials in fields like catalysis, medicine, and industrial processes, primarily benefiting chemists and researchers specializing in inorganic and organometallic chemistry.

help Alfred Werner FAQ

What did Alfred Werner's coordination theory explain?

Werner showed that metal compounds have definite three-dimensional arrangements of atoms and ligands, rather than random attachments. His 1893 work on coordination chemistry led to the 1913 Nobel Prize in Chemistry. [Nobel Prize](https://www.nobelprize.org/laureate/174)

What is a coordination compound in Alfred Werner's chemistry?

It contains a central metal ion surrounded by ligands, such as the six ammonia molecules in [Co(NH3)6]Cl3. Werner used compounds like this to explain coordination number and molecular geometry. [Nobel Prize](https://www.nobelprize.org/laureate/174)

Why is octahedral geometry linked to Alfred Werner?

Werner proposed that six ligands could occupy six positions around a central metal in an octahedral arrangement. This model helped explain the different forms of cobalt complexes and became central to coordination chemistry. [Nobel Prize](https://www.nobelprize.org/prizes/chemistry/1913/werner/facts/)

Where did Alfred Werner work when he won his Nobel Prize?

Werner was affiliated with the University of Zurich when he received the 1913 Nobel Prize in Chemistry. He was born in Mulhouse in 1866 and died in Zurich in 1919. [Nobel Prize](https://www.nobelprize.org/laureate/174)
