| 摘要: 合成了2个含有杂环硫酮的银(Ⅰ)配合物,[AgBr(PPh3)2(BTZT)]2(1),[Ag2Cl2(PPh3)2(BTZT)2]CH3OH(2)(PPh3=三苯基膦;BTZT=苯并噻唑-2-硫酮),并通过红外光谱、X射线单晶衍射、荧光光谱和核磁氢谱进行表征。2个配合物是在含有2-巯基苯并噻唑(MBT)的甲醇与二氯甲烷混合溶液中,AgX(X=Cl,Br)与三苯基膦反应得到的。MBT配体由于存在化学活性基团(-N(H)-C(=S)-),所以可以转化为BTZT配体。结构分析显示有2个相同的分子结构存在于配合物1中,但是它们具有不同的键长和键角。配合物2是一个含有菱形的[Ag2Cl2]单元在中心的反转对称二聚体,2个相邻[AgCl(PPh3)(BTZT)]单元由2个氯原子桥连。 | |

| Abstract: Two silver(Ⅰ) complexes with heterocyclic thione, [AgBr(PPh3)2(BTZT)]2 (1) and [Ag2Cl2(PPh3)2(BTZT)2]·CH3OH (2) (PPh3=triphenylphosphine; BTZT=benzothiazoline-2-thione) have been synthesized and characterized by IR, single-crystal X-ray diffraction, fluorescence spectrum and 1H NMR spectroscopy. 1 and 2 are obtained by the reactions of AgX (X=Cl, Br) with PPh3 in the presence of 2-mercaptobenzothiazole (MBT) in mixed solvent (CH3OH/CH2Cl2). The MBTligand possesses chemically active groups (-N=C(-SH)), so MBTligand can transform into BTZTligand. Structure analysis shows that there exist two same molecular structures in complex 1, but they have different bond lengths and bond angles. Complex 2 consists of inversion symmetric dimers with a diamond-shaped Ag2Cl2 group at the center, and two adjacent [AgCl(PPh3)(BTZT)] units are bridged by two Cl atoms. | |
