Definition of Dianions. Meaning of Dianions. Synonyms of Dianions

- A dianion is an anion with a net charge of −2. While there exist many stable molecular dianions, such as BeF4 2− and MgF4 2−, thus far no stable atomic...
- the second-strongest, and the para isomer is the third-strongest. These dianions were generated in a linear quadrupole ion-trap m**** spectrometer. Electrospray...
- (2000). "Ab Initio Investigation of Electron Detachment in Dicarboxylate Dianions". The Journal of Physical Chemistry A. 104 (50): 11786–11795. Bibcode:2000JPCA...
- (LiO−) was considered the strongest superbase before diethynylbenzene dianions were created. A weak base is one which does not fully ionize in an aqueous...
- superbase; only the lithium monoxide anion (LiO−) and the diethynylbenzene dianions are known to be stronger. In discussing mechanisms of organic reactions...
- is 2.45 V. Many radical anions are susceptible to further reduction to dianions. Addition of a proton source (even water) to a radical anion results in...
- activity of DBA dianions was reported by Lorbach et al. Due to the delocalization of these extra electrons in the aromatic system, the DBA dianion is formally...
- related to the disparate lattice energies of solids composed of mono- vs dianions, as well as mono- vs dications. In aqueous solution, carbonate, bicarbonate...
- is blue. The molar extinction coefficient for the blue thymolphthalein dianion is 38,000 M−1 cm−1 at 595 nm. Thymolphthalein is also known to have use...
- atom and one other element in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O2– ion with oxygen in...
