摘要

我们对在相同反应条件下获得的一系列 CuII 复合物进行了分析,以深入了解配体组成对最终反应产物的影响。研究选择了含有 N-疏基咪唑环和一个苯环作为间隔物的二极配体,这些配体的芳香环上具有不同数量的甲基取代基,如 1、3-双(咪唑-1-基甲基)苯(L1)、1,3-双(咪唑-1-基甲基)-5-甲基苯(L2)、1,3-双(咪唑-1-基甲基)-2,4,6-三甲基苯(L3)、1,3-双(2-甲基咪唑-1-基甲基)-2,4,6-三甲基苯(L4)。L4 以前未曾报道过,这次研究合成了 L4。所形成的金属配合物显示存在聚合(配体不含或含一个甲基取代基;1-4)或离散基团(3-或 5-甲基取代基;5-7)。新的金属配合物 3、5 和 6 利用单晶 X 射线衍射和粉末衍射进行了分析。此外,结构分析还得到了计算方法的支持。

Tailoring the dimensionality of metal complexes via ligand modifications.

Tailoring the dimensionality of metal complexes via ligand modifications.

A series of CuII complexes obtained under the same reaction conditions has been analyzed to gain insight into the effect of the ligand composition on the final reaction product. Dipodal ligands containing N-donor imidazole rings and a benzene ring as a spacer with different numbers of methyl substituents on the aromatic rings were selected for the study such as 1,3-bis(imidazol-1-ylmethyl)benzene (L1), 1,3-bis(imidazol-1-ylmethyl)-5-methylbenzene (L2), 1,3-bis(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (L3), 1,3-bis(2-methylimidazol-1-ylmethyl)-2,4,6-trimethylbenzene (L4). L4 has not been reported previously and was synthesized for this study. The formed metal complexes show the presence of polymeric (ligand with no or one methyl substituent; 1-4), or discrete motifs (3- or 5-methyl substituents; 5-7). The new metal complexes 3, 5 and 6 were analyzed using single-crystal X-ray diffraction and powder diffraction. In addition, the structural analyses were supported by computational methods.

期刊介绍: Acta Crystallographica Section B: Structural Science, Crystal Engineering and Materials publishes scientific articles related to the structural science of compounds and materials in the widest sense. Knowledge of the arrangements of atoms, including their temporal variations and dependencies on temperature and pressure, is often the key to understanding physical and chemical phenomena and is crucial for the design of new materials and supramolecular devices. Acta Crystallographica B is the forum for the publication of such contributions. Scientific developments based on experimental studies as well as those based on theoretical approaches, including crystal-structure prediction, structure-property relations and the use of databases of crystal structures, are published.
