Abstract

A series of 16 articles, dealing with formation of tricyanomethanide salts from nitrogen bases (amines) and tricyanomethane, turned out to be wrong because no tricyanomethane or similar compounds are used and no tricyanomethanide salts are prepared. This statement is based mainly on the recently published spectroscopic data and depicted spectra, which are completely incompatible with the claimed structures. Some of the tricyanomethanide salts are now synthesized from nitrogen heterocycles and tricyanomethane or other precursors. The corresponding products show plausible spectroscopic data and physical properties, which are entirely different to those previously reported.
