Use of Arrows in Coordination Chemistry
In a common formalism of coordination chemistry, we draw a bond from a neutral donor with a short, straight arrow. a bond from an anionic donor is shown with a straight line.
In the following structures,
- Decide whether to draw bonds with lines, or with short arrows
- Assign oxidation states to the metals.
- Fill in any missing lone pairs.
During a reaction, a ligand may change from a neutral to anionic donor, or vice versa.
- In the following reaction, illustrate electron movement with curved arrows.
-
In the following reaction, fill in oxidation states.
-
Confirm the conversion to an anionic donor upon hydride addition.
-
Add curved arrows and fill in the bridging intermediate below.
Many reactions involve single electrons. For the following reactions,
- Decide whether to draw bonds with lines, or with short arrows.
- Assign oxidation states to the metals.
- Fill in any missing lone pairs.
- Illustrate electron movement with curved arrows.
