摘要

B2Br4与S2Br2在350℃真空条件下共热解反应生成溴化硫硼烷closo-SB5Br5(1)、closo-1-SB9Br9(2)和closo-SB11Br11(3)，经高分辨率质谱、实验和计算11B核磁共振谱证实。强Brδ+（σ-空穴）⋯Brδ-（环）引力是1晶体中决定性的能量贡献。

Co-pyrolysis reactions of B₂Br₄ with S₂Br₂ at 350 °C in vacuo yielded the brominated thiaboranes closo-SB₅Br₅ (1), closo-1-SB₉Br₉ (2) and closo-SB₁₁Br₁₁ (3), confirmed by high-resolution mass spectrometry, experimental and computational ¹¹B NMR spectroscopy. The strong Br^δ+(σ-hole)⋯Br^δ−(ring) attraction has been the decisive energy contribution in the crystal of 1.
