  Novel Binary Compounds of Group 15 Elements: Synthesis and Characterisation of [Sb ₄ (PSiMe ₂ Thex) ₄ ], [Sb ₄ (AsSi i Pr ₃ ) ₄ ] and [Sb ₂ (PSiPh ₂ t Bu) ₄ ]

  摘要：

  AbstractThe low‐temperature reactions of Me2ThexSiPLi2 (Thex = CMe2iPr) and iPr3SiAsLi2 with SbCl3 in a 3:2 molar ratio yields the cage compounds [Sb4(PSiMe2Thex)4] (1) and [Sb4(AsSiiPr3)4] (2), respectively. The metal salt SbBr3 reacts with tBuPh2SiPLi2 at −70 °C to give the bicyclic compound [Sb2(PSiPh2tBu)4] (3). Compounds 1−3 were characterised by NMR and IR spectroscopy, mass spectrometry, elemental analysis and single‐crystal X‐ray diffraction. The structures of 1 and 2 reveal that the both compounds adopt a structure similar to those of realgar (As4S4). The central structural motif is an Sb4Y4 cage (Y = P, As), consisting of four five‐membered rings with common edges. The bicyclic compound 3 is composed of five‐membered and three‐membered rings sharing a common Sb2 bridgehead. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
