摘要: 合成了2个含有杂环硫酮的银(Ⅰ)配合物,[AgCl(PPh₃)₂(BTZT)]₂ (1),[Ag(PPh₃)₂(BTZT)₂](NO₃)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、荧光光谱和核磁共振氢谱进行表征和分析。杂环硫酮存在化学活性基团-N(H)-C(=S)-,在平衡中与其硫醇形式可以相互转化。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,AgCl或AgNO₃与三苯基膦反应得到的。配合物1的每个不对称单元中包含2个相同的分子结构,但是它们具有不同的键长和键角。配合物2是一个简单的单核杂配配合物,它的主体结构通过氢键作用连接游离的CH₃OH和NO₃^-离子。配合物1和2发射峰的红移源于配体中的π-π^*跃迁。

Abstract: Two silver(Ⅰ) complexes with heterocyclic thione, [AgCl(PPh₃)₂(BTZT)]₂ (1) and [Ag(PPh₃)₂(BTZT)₂](NO₃)·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. Heterocyclic thiones possess chemically active groups -N(H)-C(=S)- in equilibrium with its thiol form. 1 and 2 are obtained by the reactions of AgCl or AgNO₃ with PPh₃ in the presence of 2-mercaptobenzothiazole (MBT) in mixed solvent (CH₃OH/CH₂Cl₂). The complex 1 contains two same structures in each asymmetric unit, but there are different bond lengths and bond angles. Complex 2 is a simple mono-nuclear heteroleptic complex whose main structure links free CH₃OH and NO₃^- anion by hydrogen bonding interactions. The red-shift of emission peak of 1~2 is derived from ligand-centered π-π^* transition. CCDC: 1059719, 1; 1059720, 2.
