Abstract
The cation of the title compound, 3,5-bis(2-methylphenyl)-1,2, 4-dithi azolylium hexafluoroarsenate(V), C16H14NS2+AsF6-, has a central planar five-membered NCSSC ring with two o-tolyl substituents lying 29.11 (9 )degrees out of this plane because of the steric hindrance of the meth yl groups. The cation has a twofold rotation axis through the N atom a nd the midpoint of the S-S bond. Interionic interactions include short S ... F and N ... F contacts, but the cations are well separated with no S ... S or N ... S interactions.
