Electronic states and stability of GeC2N radical

Electronic states of the GeC2N radical are explored at various theoretical levels which revealed ten minimal energy isomers and 10 interconversion transition states. The thermodynamically most stable isomer is a linear form GeCCN 1 which is qualitatively described as a resonance hybrid of ∣GeCCN∣, ∣GeC-CN∣, and ∣GeCCN∣.
