Dianion - Wikipedia
A dianion is an anion with a net charge of −2. While there exist many stable molecular dianions, such as BeF4 and MgF4 , thus far no stable atomic dianion has been found: Electron shielding and other quantum mechanical effects tend to make the addition of another electron to an atomic anion unstable.
The most heavily studied atomic dianion is H , usually as a short-lived resonance between an electronWikipedia · Text under CC-BY-SA license- Estimated Reading Time: 1 min
Diethynylbenzene dianion - Wikipedia
In organic chemistry, a diethynylbenzene dianion is an anion consisting of two ethynyl anions as substituents on a benzene ring. With the chemical formula C 6H 4C 4, three positional isomers are possible, differing in the relative positions of the two substituents around the ring:
