Abstract
Selenourea was investigated in the binary superacidic media XF/MF5 (X = H, D;M = As, Sb). The protonation selectively takes place at the selenium atom leading to the corresponding salts [(X2N)(2)CSeX](+)[MF6](-). The characterization of the colorless salts was performed by low temperature vibrational spectroscopy. In the case of [(H2N)(2)CSeH](+)[SbF6](-) a single-crystal X-ray structure analysis is reported. The observed Se center dot center dot center dot F interaction in the solid state is discussed in context of sigma-hole interactions. Selenourea undergoes structural changes due to the protonation which are discussed together with quantum-chemical calculations.
