双(苯并咪唑-2-叶立德)蒽-汞(Ⅱ)配合物的合成和结构

Synthesis and Structural Characterization of the Bis(benzimidazolin-2-ylidene)Anthracene-Mercury(Ⅱ)Complexes

N-丁基苯并咪唑与9,10-二(氯甲基)蒽在加热条件下反应生成氮杂环卡宾盐,接着与六氟磷酸钾进行阴离子交换,形成双(苯并咪唑-2-叶立德)蒽六氟磷酸盐配体1,再将配体1和氧化汞反应生成双(苯并咪唑-2-叶立德)蒽-汞(Ⅱ)配合物2。通过1 H NMR、13 C NMR和单晶衍射确定其分子结构,对配体1和配合物2的紫外和荧光性质进行了研究。

Reaction of N-buthylbenzimidazole and 9, 10- bis（chloromethylene） anthracene at heat attorded benzimidazohum salts. Treatment of the dibenzimidazolium chloro salts with potassium hexafluorophospate yielded bis （benzimidazolin-2-ylidene） anthracene hexafluorophospate 1 by anion-exchanged, and then it reacted with HgO to give bis （benzimidazolin-2-ylidene） anthracene-mercury（II） complexes in high yields. The structure of complex was determined by 1 H NMR, 13 C NMR and X-ray diffraction. UV-vis absorption and fluorescent properties of ligand 1 and complex 2 were discussed, too.
