The reactions of silicon atoms with cyanogen 12 in an argon matrix at 10 K have been studied. In the initial step a triplet n adduct T-13 is formed between a silicon atom and 12. The next step needs photochemical activation. Long-wavelength irradiation yields 3-cyanoazasilacyclopropenylidene 14, which upon irradiation with 254 nm light is transformed into three isomeric silylenes: dicyanosilylene 15
