According to X-ray crystallography, the two C₂H₅OC(S)S) groups in solid diethyl dixanthogen disulfide are planar and are linked by a disulfide bond. The C-S-S-C dihedral angle is near 90°, as is common for acyclic disulfides.^[1]

Occurrence and reactions

Diethylxanthogen reacts with aqueous base to regenerate the xanthate, at least partially.^[4]

Diethylxanthogen arises by oxidation of xanthates during froth flotation. Diethylxanthogens are thought to participate in the flotation of certain sulfide minerals.^[5]
