The structure of trityl persulfide has been determined by X-ray crystallography.  The S-S bond length is 204 picometers and the C-S-S-H dihedral angle is 82°. These parameters are unexceptional.  (CH)CSSH behaves as a source of sulfur, illustrated by its reaction with triphenylphosphine to give triphenylphosphine sulfide and triphenylmethanethiol:  
:(CH)CSSH  +  P(CH)  →   (CH)CSH  +  SP(CH)
