Crystal and molecular structure of dibenzoyl disulfide

Synthesis, structural, and spectral studies of N,N′-bis- (5-methylsalicylidene)-2,2′-diamino-4-4′-di-(trifloromethyl)-diphenyl disulfide

“…This bond NH CH F 3 C S + Fig. 2 Main fragment in the mass spectrum length is in agreement with those reported for analogous structures [30][31][32]. The comparison of S-S bond lengths and the other main structural parameters around S-S bond are given in Table 4.…”

Bis(N-methyl-N-phenylcarbamoyl)disulfane

“…The most noteworthy feature of the title compound is the torsion angle about the disulfane, which is 81.6° and as such is somewhat smaller than the theoretical optimum of 90.0° (Pauling, 1949;Torrico-Vallejos et al, 2010) that has been explained as allowing for minimal mutual repulsion of pπ orbital electron lone pairs in sulfur. A comparable deviation from theory was reported for dibenzoyl disulfide (Rout et al, 1983;Paul & Srikrishnan, 2004), where the torsion angle is 80.8°. Bis(Nmethyl-N-phenylthiocarbamoyl)disulfane, which only differs from the title compound by two thiocarbonyls in place of two carbonyls, has a torsion angle about the disulfane of 89.8° and shows a conformation that is not completely superimposable on the title compound (Fun et al, 2001).…”

“…Several other reference compounds also have an S-S bond length of 2.01-2.03 Å (Bereman et al, 1983;Rout et al, 1983;Paul and Srikrishnan, 2004;Fun et al, 2001;Raya et al, 2005;Li et al, 2006;Singh et al, 2011). The most noteworthy feature of the title compound is the torsion angle about the disulfane, which is 81.6° and as such is somewhat smaller than the theoretical optimum of 90.0° (Pauling, 1949;Torrico-Vallejos et al, 2010) that has been explained as allowing for minimal mutual repulsion of pπ orbital electron lone pairs in sulfur.…”
