Abstract :
The crystal structure of the title compound has been determined. The compound crystallized in the triclinic space group P -1, Z = 2, V = 1839.42(18) Nandunit cell parameters a= 11.0460(6) A, b = 13.3180(7) A, c = 13.7321(8)A,a= 80.659(3)°, b= 69.800(3)° andg= 77.007(2)° with one disordered dimethylsulfoxide solvent molecule with the sulfur and oxygen atoms are distributed over two sites; S lOllS 102 [site occupancy factors: 0.6035/0.3965] and 0130/0 131 [site occupancy factor 0.3965/0.6035]. The C22-S21 and C19-520 bond distances of 1.779(7)Aand 1.788(8)Aindicate that both of the molecules are connected by the disulfide bond [S20-S21 2.055(2) A] in its thiol form. The crystal structure reveals that both of the 5-bromoisatin moieties are trans with respect to the [S21-S20 and CI9-NI8] and [S20-S21 and C22-N23] bonds whereas the benzyl group from the dithiocarbazate are in the cis configuration with respect to [S21-S20 and C19-544] and [S20-S21 and C22-S36] bonds. The crystal structure is further stabilized by intermolecular hydrogen bonds of N9-H35°O 016 formed between the two molecules and N28-H281 ..·0130, N28-H281 00·0131 and C41-H411 0 131 with the solvent molecule.
