Chemical syntheses of poly(sulphur nitride), (SN) x

The preparation and X-ray crystal structure of Te(N3)3SbF6 containing the triazidotellurium(IV) cation, Te(N3)3+

“…The S2N+ cation, in S2NAsF6 (1) has a rich chemistry, and is an important building block in the systematic synthesis of other sulfur-nitrogen-containing compounds (2)(3)(4)(5)(6)(7)(8)(9). It would be of interest to prepare the selenium and tellurium analogues, Se2NAsF6 and Te2NAsF6, as they should also have extensive chemistries, because they are of interest in their own right and because very few isolated selenium-nitrogen or telluriumnitrogen species exist.…”

Neutral binary chalcogen–nitrogen and ternary S,N,P molecules: new structures, bonding insights and potential applications

“…Although this barrier is considerably higher than the value of 7 kcal mol −1 determined for the decomposition of cyclo-SN 4 (section 4.2), the facile formation of S 2 N 2 from decomposition of SNSNNN (14) may account for the rapid production of (SN) x observed in the reaction of [SNS][AsF 6 ] with CsN 3 in SO 2 (l) at −20°C. 45 As a general conclusion, it is important to note that kinetic stability is more important than thermodynamic stability in determining which binary sulfur-nitrogen species can be isolated under ambient conditions. The isomers of the nitrogenrich cation [S 2 N 3 ] + a 6π-electron system, provide a compelling example of this principle.…”

Formation of Chalcogen–nitrogen Bonds

“…Thus the reaction of S 2 Cl 2 with sodium azide in acetonitrile followed by treatment of the [S 3 N 2 ]Cl produced with Me 3 SiN 3 yields (SN) x as a black solid. 30 33 Organosulfur(II) azides evolve N 2 spontaneously at room temperature. For example, the reaction of CF 3 SCl with Me 3 SiN 3 produces the, presumably cyclic, tetramer (CF 3 SN) 4 .…”
