Thiocyanogen, (SCN)2, is a pseudohalogen derived from the pseudohalide thiocyanate, [SCN]−, with behavior intermediate between dibromine and diiodine.[2] This hexatomic compound exhibits C2 point group symmetry and has the connectivity NCS-SCN.[3]
In the lungs, lactoperoxidase may oxidize thiocyanate to thiocyanogen[4] or hypothiocyanite.[5]
