Abstract
Abstract The reactions of antimony trichloride with excess triethylylaluminum and with diethylaluminum chloride have been studied. The former reaction gives the complex [SbEt4] [Al2Et5Cl2] and the latter the complex [SbEt4] [AlCl4]. A series of the organometallic complexes containing antimony and aluminum has been prepared by the reactions of quinquevalent ethylantimony halides, i.e. triethylantimony dihalide, tetraethylstibonium halides with various aluminum compounds, AlEtnCl3-n. The proposed formulas of these complexes are shown as [SbEt4] [AlEtnX4-n] (I), [SbEt4] [Al2EtnX7-n] (II) and SbEt3X2-nAIX3 (III), where X is halogen. The former two are thought to be ionic stibonium complex salts and the latter simple adducts. The behavior of 1:1 complex (I) for aluminum alkyls has further been clarified. Triethylstibine also forms various complexes with aluminum compounds, AlEtnCl3-n. The proposed formulas of these complexes are shown as mSbEt3-nAlEtm, Cl3-m, (IV) and SbEt3-SbEt2Cl-AlCl3 (V). The ionic properties of complexes (IV) have been elucidated.
