The (SO₂)₂N₃^- Anion

Abstract

The recently proposed (SO2)2N3- anion was structurally characterized by single-crystal X-ray diffraction of the [Cs][(SO2)2N3] salt (P2(1)/c, a = 8.945(2) A, b = 10.454(2) A, c = 8.152(2) A, beta = 109.166(3) degrees, Z = 4, and R1 = 0.0329 at 130 K). In the (SO2)2N3- anion, both SO2 ligands are coordinated to one terminal nitrogen atom of the N3- anion.

SF4·N(C2H5)3: the first conclusively characterized SF4 adduct with an organic base

“…The signals of both moieties are shifted and exhibit splittings compared to those of the parent Lewis acid and base. Gaseous SF 4 has C 2v symmetry, with the symmetric and asymmetric n(S-F 2 ) 606 (7) 644 (1)[467] n(S-F 3 ) À n(S-F 4 ) 513 (11) 481(2…”

Recent Advances in the Chemistry of N5+, N5− and High‐Oxygen Compounds

“…To clarify this startling observation, the SO 2 /azide system was thoroughly characterized. It was found that SO 2 forms well defined 2 : 1 and 1 : 1 adducts with the N 3 À anion [19,20]. In addition, the crystal structure of the SO 3 N 3 À anion was also determined [19].…”
