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(1H 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.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(DBPMC2)as axial ligands,four rhodium(Ⅱ)carboxylates axial dibromo-9-pyridylmethyl-9H-carbazole complexes Rh 2(OOCR)4(DBPMC)2 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 1H NMR,13 C 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.
