Photolysis of dicyanodiazomethane in Ar matrices has been studied. Dicyanomethylene appears to be the sole product in dilute matrices, and its UV absorption spectrum and a revised IR spectrum are reported. In O2-doped Ar matrices, dicyanomethylene reacts with O2 to give carbonyl cyanide O-oxide as a very photolabile adduct. Four IR bands and a broad UV absorption at 375 nm are assigned to this species. On further photolysis, the carbonyl oxide rapidly decomposes to give carbonyl cyanide, by O-atom expulsion. A strong product absorption at 585 nm is assigned to a charge-transfer complex involving the expelled oxygen, but the precise nature of this species remains unknown.
