Here, we describe a magnetic resonance spectroscopy characterization of selenium cyanide compounds, Se(CN)2, Se2(CN)2 and Se3(CN)2. Selenim-77 and carbon-13 nuclides were used to provide data of these species at room temperature. This is the first structural characterization performed using NMR for Se3(CN)2, while only low-temperature analyses have been conducted so far for Se(CN)2 and Se2(CN)2. Based on these limitations, a characterization study was deemed mandatory, especially from a synthetic chemistry point of view. In addition to these analyses, we carried out a purity assessment for Se3(CN)2 according to the melting point parameter along with a solubility evaluation.
