|
The reaction of hydrazine hydrate with carbon disulfide and 4-methylbenzyl chloride in basic solution yielded 2,5-bis(4-methylbenzylthio)-1,3,4-thiadiazole (C18H18N2S3, compound 1) in addition to the expected S-4-methylbenzyldithiocarbazate. The molecule has approximate twofold symmetry with the C=S bond lying on the pseudo axis. The five membered ring is planar with the three S atoms mutually syn, andwith pendent 4-methylbenzylthio substituents; the dihedral angle between the terminal rings is 52.21(7). The compound 1 crystallizes in the triclinic space group P1 with a = 6.0139(3) A ° , b = 11.8694(7) A ° , c = 12.6330(7) A ° , a = 72.583(5), b = 82.827(4), c = 89.882(4) and Z = 2.
