  Alternative and, in some cases, improved syntheses of the salts MX₃(As/Sb)F₆ (M = S, Se) and SCl₃(SbCl₆/AlCl₄) are described. In addition, the synthesis of SeCl₃SbF₆ is reported. The compounds were characterized by FT–Raman spectroscopy and the X-ray crystal structures of SeCl₃AsF₆ (also ⁷⁷Se NMR) and a new phase of SBr₃SbF₆ were determined. Crystals of SeCl₃AsF₆ and SBr₃SbF₆ are monoclinic, space group P2₁/c with [values for SBr₃SbF₆ in brackets] a = 7.678(1) [8.137(1)] Å, b = 9.380(3) [9.583(2)] Å, c = 11.920(3) [12.447(2)] Å, β = 98.19(2)° [97.36(1)]°, V = 849.72(3) [962.6(3)] ų,z = 4, D_x = 2.925 [3.502] Mg m⁻³, R = 0.0525 [0.055], and R_w = 0.0554 [0.060] for 1151 [1472] observed reflections.

• A ¹⁹F nuclear magnetic resonance study of the conjugate Brönsted-Lewis superacid HSO₃F-SbF₅. Part 1

  The Brönsted-Lewis superacid HSO₃F-SbF₅ or "magic acid" is re-investigated by modern ¹⁹F NMR methods over a wide concentration range. The system is found to be considerably more complex than had been assumed previously. A total of 13 different anions are identified of which only five have previously been identified in magic acid. With increasing SbF₅ contents the concentration of monomeric anions like [SbF₆]^-, [SbF₅(SO₃F)]^-, cis- and trans-[SbF₄(SO₃F)₂]^-, and mer-[SbF₃(SO₃F)₃]^- gradually decreases. Except for [Sb₂F₁₁]^-, which is present in very small concentrations only, the formation of oligomers involves exclusively μ-fluorosulfato bridges. In addition to donor (SO₃F)^- and acceptor (SbF₅) complex formation to give [SbF₅(SO₃F)]^- and possibly ligand redistribution, the solvolysis of SbF₅ or SbF₄(SO₃F) in HSO₃F appears to be the principal formation reaction for polyfluorosulfatofluoroantimonate(V) anions. In glass (NMR tubes) the solvolysis product HF is converted to the oxonium ion [H₃O]⁺, which has previously been identified by ¹H NMR and structurally characterized as [H₃O][Sb₂F₁₁] by us.Key words: magic acid, conjugate superacid, fluorosulfuric acid, ¹⁹F NMR spectra.

  Brönsted-Lewis超酸HSO3F-SbF5或“魔法酸”通过现代19F NMR方法在广泛的浓度范围内进行了重新研究。该体系被发现比先前假定的要复杂得多。总共识别出13种不同的阴离子，其中仅有五种先前在魔法酸中被确认。随着SbF5含量的增加，单聚合物阴离子的浓度如[SbF6]-，[SbF5(SO3F)]-，顺式和反式-[SbF4(SO3F)2]-以及mer-[SbF3(SO3F)3]-逐渐减少。除了仅以极小浓度存在的[Sb2F11]-外，寡聚物的形成仅涉及μ-氟磺酸桥。除了供体(SO3F)-和受体(SbF5)形成络合物以生成[SbF5(SO3F)]-并可能进行配体重新分配外，SbF5或SbF4(SO3F)在HSO3F中的溶解似乎是多氟磺酸氟锑酸盐(V)阴离子的主要形成反应。在玻璃(NMR管)中，溶解产物HF转化为氧离子[H3O]+，该离子先前已被我们通过1H NMR鉴定并结构化为[H3O][Sb2F11]。关键词：魔法酸，共轭超酸，氟磺酸，19F NMR谱。

Two diastereomers (i.e., (2,0) and (1,1)-forms) are possible for Pd2L′2Lun2 type complex, whereas four diastereomers (i.e., (4,0), (3,1), trans(2,2), and cis(2,2)-forms) can be imagined for the Pd2Lun4 type complex. However, exclusive diastereoselectivity was observed, and the complexes formed belong to (1,1)-Pd2L′2Lun2 and cis(2,2)-Pd2Lun4 forms. The diastereomers
