Dicyanocarbodiimide and Trinitreno‐s‐triazine Generated by Consecutive Photolysis of Triazido‐s‐triazine in a Low‐Temperature Nitrogen Matrix

Carbon nitride molecules: Photolysis (λ=266 nm) of triazido-s-triazine (C3N12, 1) in a nitrogen matrix at 20 K yielded a succession of reactive species (see scheme), including, in order, an apparent trinitrene, NCN, and a novel C3N4 isomer, dicyanocarbodiimide NCNCNCN.
