Abstract

Lead(II) complexation reactions were studied in the presence of salts of the closo-decaborate anion [B₁₀H₁₀]^2– and azaheterocyclic ligands 2,2'-bipyridyl (bipy) or 1,10-phenanthroline (phen) in water and organic solvents (acetonitrile, DMF). Binuclear complex Pb(bipy)₂[B₁₀H₁₀] and polymer complex [Pb(phen)[B₁₀H₁₀]] were isolated. The effect of solvents and reagent ratios on the composition and structures of the final complexes was studied. The complex compounds were identified by elemental analysis, IR spectroscopy, and X-ray powder diffraction. The structure of complex [Pb(bipy)₂[B₁₀H₁₀]]₂·2CH₃CN (CCDC no. 2325841) was determined by single-crystal X-ray diffraction.

十氢-氯-癸硼酸阴离子和氮杂环配体的混合配体铅（II）配合物的合成及其结构

在水和有机溶剂（乙腈、DMF）中，研究了闭癸硼酸阴离子 [B10H10]2- 和杂杂环配体 2,2'-联吡啶（bipy）或 1,10-菲罗啉（phen）盐存在下的铅（II）络合反应。分离出了双核络合物 Pb(bipy)2[B10H10] 和聚合物络合物 [Pb(phen)[B10H10]]。研究了溶剂和试剂比例对最终络合物组成和结构的影响。通过元素分析、红外光谱和 X 射线粉末衍射对复合物进行了鉴定。通过单晶 X 射线衍射确定了[Pb(bipy)2[B10H10]]2-2CH3CN（CCDC 编号：2325841）复合物的结构。
