Unexpectedly stable is ethynyl isocyanide 1 , the parent compound of the hither‐to unknown alkynyl isocyanides. It is storable at −196°C for several weeks and at room temperature for several days in the gas phase. Compound 1 is obtained by flash vacuum pyrolysis of the chromium complex 2 . The microwave data of 1 described in this communication enabled it to be detected (after submission of this paper) in interstellar space by radioastronomy where other nitrogen‐containing isomeric pairs consisting of uncharged closed‐shell molecules, as well as its isomer HCCN, abound.
