Thiocyanogen, (SCN)2, is a pseudohalogen derived from the pseudohalide thiocyanate, [SCN]−, with behavior intermediate between dibromine and diiodine. This hexatomic compound exhibits C2 point group symmetry and has the connectivity NCS-SCN.
In the lungs, lactoperoxidase may oxidize thiocyanate to thiocyanogen or hypothiocyanite.
