5,6-Dihydro-5,6-diphenyl-1,3-dithiolodithiine-2-thione (DHPT-DTT), C17H12S5

Qi, Fang,Wen-Tao, Yu,Jian-Hua, Xu,Hong, Lei,Min-Hua, Jiang

, p. 1519 - 1522 (1994)

the DHPT-DTT molecule contains a conjugated 4,5-dimercapto-1,3-dithiole-2-thione plane and two phenyl planes, all of which are approximately perpendicular to one another.The crystal packing is stabilized by an S...S interaction between pairs of neighbouring molecules, which may account for the rather high thermal stability of the crystal.
