Dreiding stereo model
Dreiding stereo models are molecule models that have been used in research and teaching to illustrate stereochemical analyzes or reaction mechanistic considerations. They were developed by André Dreiding in 1958 .
The units consist of stainless steel rods and tubes that are soldered together at a color-coded central point representing the atomic nucleus (color indicates the respective element ). The nested rods and tubes of a unit mark the sigma bonds ( σ bonds ) in the model of a molecule. The bond lengths and angles are depicted very realistically and vividly and allow a visual and haptic understanding. The Dreiding stereo models were sold by Büchi Labortechnik and Koch-Light.
Today, instead of the Dreiding stereo models, 3D computer simulations are often used to illustrate stereochemical facts.
