The missing link in the 28‐electron family of open‐chain N 4 , N 2 CO, and C 2 O 2 molecules has been detected in the gas phase as an isolated, intact N 2 CO species, whose lifetime exceeds 0.8 μs. The new metastable molecule has been prepared by neutralization–reionization mass spectrometry of labeled N 2 CO + ions, which were generated in various N 2 /CO ionized mixtures (see picture).
