  • n. Any anion carrying two negative charges


Sorry, no etymologies found.


  • I dabbled in cyclooctatetraene chemistry and synthesized compounds such as the anion of triscyclooctatetraene niobium, and blue Ta (C8H8) Me3, prepared through addition of the dianion of cyclooctatetraene to tantalum trimethyldichloride, the only known alkyl of tantalum, which had been reported by G.L. Juvinall in 1964.

  • The primary species of bound UCB in our models were: undissociated diacid for phosphatidylcholine, dianion for dodecyl maltoside micelles and cyclodextrins, and both monoanions and dianion for sodium taurocholate.

  • These analyses indicated that the high pKa values, dianion dimerization constant and solubilities of UCB at various pH values, derived from our partition studies, along with literature-derived pH - and time-dependent supersaturation effects, were essential for constructing useful models that showed good qualitative, and sometimes quantitative, fits with the data.
