摘要:选择乙酸铑(Ⅱ)、三甲基乙酸铑(Ⅱ)为主体,以3,6-二溴-9-(4-吡啶甲基)-9H-咔唑(DBPMC1)、3,6-二溴-9-(3-吡啶甲基)-9H-咔唑(DBPMC2)为轴向配体,设计并合成了4种羧酸铑(Ⅱ)轴向二溴-9-吡啶甲基-9H-咔唑配合物Rh2(OOCR)4(DBPMC)2,并成功培养其单晶;采用现代分析手段,如核磁共振H谱(H NMR)、核磁共振C谱(13C NMR)和傅里叶变换红外光谱(FT-IR)等初步表征了4种配合物的化学结构.结果表明,这4种化合物均未见有文献报道,属新型羧酸铑(Ⅱ)轴向配合物.通过X射线单晶衍射分析确定,配合物是由一分子的羧酸铑(Ⅱ)和两分子的DBPMC配体配位而成,所得结构符合预期实验设计.

Abstract: Using rhodium(Ⅱ) acetate and trimethylrhodium acetate(Ⅱ) as the raw material,with 3,6-dibromo-9-(4-pyridinemethyl)-9H-carbazole (DBPMC1) and 3,6-dibromo-9-(3-pyridinemethyl)-9H-carbazole (DBPMC) as axial ligands,four rhodium(Ⅱ) carboxylates axial dibromo-9-pyridylmethyl-9H-carbazole complexes Rh(OOCR)4(DBPMC) were designed and synthesized.The single crystals of compounds were successfully cultured and their chemical structures were initially characterized by modern analytical methods such as H NMR,13C NMR and FT-IR.The results show that none of these four compounds has been reported in the literature,and they belong to a new type of rhodium carboxylate (Ⅱ) axial complex.The structure of the complex was determined by X-ray single crystal diffraction analysis to be composed of one molecule of rhodium(Ⅱ) carboxylate and two molecules of DBPMC ligand,and the molecular structure diagram and unit cell stacking diagram were drawn.

Key words: rhodium(Ⅱ) acetate, axial coordination, crystal structure, molecular structure diagram, cell stacking diagram
