2-(Dicyanomethylene)croconate
}}
2-(Dicyanomethylene)croconate is a divalent anion with chemical formula or ((N≡C-)2C=)(C5O4)2−. It is one of the pseudo-oxocarbon anions, as it can be described as a derivative of the croconate oxocarbon anion through the replacement of one oxygen atom by a dicyanomethylene group =C(-C≡N)2.
The anion was synthesized and characterized by A. Fatiadi in 1980, by hydrolysis of croconate violet treated with potassium hydroxide.〔Alexander J. Fatiadi (1980), ''Pseudooxocarbons. Synthesis of 1,2,3-tris(dicyanomethylene)croconate salts. A new bond-delocalized dianion, croconate blue''. Journal of Organic Chemistry volume 45, pages 1338-1339.
〕 It gives an orange solution in water.
