Bismuth ladder polymers: structural and thermal studies of [Bi(OCH2CH2)3N]n and [(BixTb1−x(O2C2H2)3N·2H2O]n
摘要:
[Bi(OCH2CH2)(3)N],(Bi(TEA)), may be prepared by reaction of in situ generated Bi(OH)(3) with triethanolamine in refluxing methanol. The complex crystallizes from solution as a double ladder polymer via the formation of additional metal-oxygen dative bonds to yield hypercoordinate and hypervalent metal centers. The structure of Bi(TEA) is very similar to that of Bi(O2CCH3)(3)N. The heterobimetallic nitriloacetate complex containing Bi and Tb was prepared by reaction of (NH4)(3)[Bi(Nta)(2)] with terbium nitrate in aqueous solution. Heating samples of [Bi(OCH2CH2)(3)N](n) to 1000 degreesC results in the formation of Bi2O3. It was shown that thermolysis of the [(BixTb1-x(O2C2H2)(3)N).H2O](n) occurs in two stages, viz. the deaquation and pyrolysis of the ligand. (C) 2002 Elsevier Science B.V. All rights reserved.

Abstract Functional Bi alkoxides were prepared by reaction between the oxide and diols such as N-methyldiethanolamine (mdeaH2), diethanolamine (deaH2) and triethanolamine (teaH3) in refluxing toluene in high yields. Similar reactions with polyols without N-donor site lead to oxo species. The derivative obtained with N-methyldiethanolamine was characterised by X-ray diffraction as a dimer [Bi2(mdea)2(mdeaH)2]
摘要 将氧化物与N-甲基二乙醇胺(mdeaH2)、二乙醇胺(deaH2)、三乙醇胺(teaH3)等二元醇在回流甲苯中高产率反应制备功能性双醇盐。与没有 N 供体位点的多元醇的类似反应会产生含氧物种。用 N-甲基二乙醇胺获得的衍生物通过 X 射线衍射表征为二聚体 [Bi2(mdea)2(mdeaH)2],通过 H 键与中性二醇分子结合成链,得到标题化合物。铋是伪 7 坐标。Bi-O 键距范围从 2.150(5) 到 3.093(5) A,具有三个短键,而跨环 Bi-N 键距为 2.737 A av。报道了热解和水解反应。
