Abstract
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DB-PMC配体配位而成,所得结构符合预期实验设计.
