Selenourea was investigated in the binary superacidic media X F/ M F 5 ( X = H, D; M = As, Sb). The protonation selectively takes place at the selenium atom leading to the corresponding salts [( X 2 N) 2 CSe X ] + [ M F 6 ] – . The characterization of the colorless salts was performed by low temperature vibrational spectroscopy. In the case of [(H 2 N) 2 CSeH] + [SbF 6 ] – a single‐crystal X‐ray structure analysis is reported. The observed Se ··· F interaction in the solid state is discussed in context of σ‐hole interactions. Selenourea undergoes structural changes due to the protonation which are discussed together with quantum‐chemical calculations.
