 Title    Element—Element-Bindungen, III [1] Intermolekulare Sb-** Sb-Wechsel Wirkungen im kristallinen Tetramethyldistiban1 Elem ent—Elem ent Bonds, III [1] Intermolecular S b--S b Interactions in Crystalline Tetram ethyldistibane  
 Abstract    Tetramethyldistibane which shows a colour change from deep red to pale yellow upon melting, has been subjected to single-crystal x-ray diffraction analyses at —21° and —139 °C (orthorhom-bic, Pnma, Z = 4, —139 °C: a = 1150.9(3); b = 1136.8(2) ; c = 651.6(2) pm). The molecules adopt the antiperiplanar conformation with the crystallographically imposed symmetry m (Cs) and are aligned in extended linear antimony chains with short intermolecular contacts (—139 °C: Sb—Sb 283.8(1), Sb--Sb 367.8(1) pm; Sb—Sb---Sb 179.2°). The structure is compared with those of similar compounds.
