This colourless solid is a useful reagent in organic synthesis. The structure of this compound is complex, possibly time-dependent, and may depend on solvent. ==Structure== The structure of the metal alkoxides are often complex and aluminium isopropoxide is no exception. The complexity is also reflected in the disputed melting point for the material which could reflect the presence of trace impurities, such as water, slow oligomerisation ("aging") or both. For aluminium isopropoxide this phenomenon is mainly due to the trimer-tetramer transformation described in detail in the early works by Turova et al. The tetrameric structure of the solid crystalline material was verified by NMR spectroscopy and X-ray crystallography. The species is described by the formula Al(μ-O-i-Pr)2Al(O-i-Pr)23.〔Turova, N. Y.; Kozunov, V. A.; Yanovskii, A. I.; Bokii, N. G.; Struchkov, Yu T.; Tarnopolskii, B. L. Journal of Inorganic and Nuclear Chemistry 1979, volume 41, p. 5.〕 The unique central Al is octahedral surrounded by three bidentate "Al(O-i-Pr)4−" ligands, each featuring tetrahedral Al. The idealised point group symmetry is ''D3''. The tert-butoxide is a dimer with the formula Al2(μ-O-t-Bu)2(O-t-Bu)4 It is prepared analogously to the isopropoxide. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aluminium isopropoxide」の詳細全文を読む スポンサード リンク
