Formation of an adduct between thiocyanate ion and nitrosyl thiocyanate

Abstract

Nitrosyl thiocyanate reacted with sufficiently high concentrations of thiocyanate ion to form an adduct, [ON(SCN) ₂ ] ^- , which absorbs strongly in the UV region. This species has different properties to that species described in the literature as [NO(SCN) ₂ ] ^- formed in pulse-radiolysis experiments involving (SCN) ₂ ^- and NO. The difference probably arises from different structures, an S-nitroso as compared to an N-nitroso compound.
