Abstract: The title salt, C₂₀H₄₂N₄S₂²⁺·2ClO₄^-, was obtained from the reaction of bis(diethylamino)carbeniumdithiocarboxylate, (Et₂N)₂C₂S₂, with Fe(ClO₄)₂·6H₂O in CH₂Cl₂. The title compound, in which one of the S atoms of (Et₂N)₂C₂S₂ is bound to a 1,1-bis(diethylamino)ethane moiety, has two carbenium C atoms, and the charge compensation is provided by two perchlorate anions. The N₂C-CS₂ bond length is 1.512 (4) Å, corresponding to a C-C single bond, and the dihedral angle between N₂C- and -CS₂ planes [72.0 (2)°] is smaller than that of (Et₂N)₂C₂S₂ [82.0 (1)°]. The crystal structure features C-HS hydrogen bonds.
