| 摘要: 金属卤化物MCl2（M=Pb2+，Cd2+，Co2+）分别与苯并噻唑（btz）在浓盐酸中、80 ℃下反应，合成了3种有机-无机杂化化合物：（btzH）[（PbCl3）] （1），（btzH）2[CdCl4]·2H2O （2）和（btzH）2[CoCl4]·2H2O （3），其中化合物2和3结构相似。对化合物1~3进行了粉末衍射、红外和紫外光谱、元素分析、热重分析以及X射线单晶衍射表征。荧光测试发现：化合物1~3在393 nm处有发射峰，该荧光来源于苯并噻唑环中电子的π…π跃迁。 |

| Abstract: The reaction of three divalent metal (Ⅱ) halides MCl2 (M=Pb2+, Cd2+, Co2+) with two equivalents of benzothiazole (btz) in the concentrated acid HCl at 80 ℃ resulted in the formation of the corresponding organic-inorganic hybrid compounds: (btzH)[(PbCl3)] (1), (btzH)2[CdCl4]·2H2O (2) and (btzH)2[CoCl4]·2H2O (3), in which the structures of compounds 2 and 1 are similar. All compounds have been characterized by XRD, IR, UV-Vis, EA, TG and single X-ray diffraction. Fluorescent investigation reveals that compounds 1~3 exhibit similar emission peaks at 393 nm, which are ascribed to the π…π transition of the btz ring. |
