合成了2个含有杂环硫酮的银(Ⅰ)配合物,[Ag Cl(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,Ag Cl或Ag NO3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。
Two Ag (PPh3) 2 (BTZT)] 2 (1), [Ag (PPh3) 2 (BTZT) 2] (NO3) ) (PPh3 = triphenylphosphine; BTZT = benzothiazole-2-thione) and characterized and analyzed by infrared spectroscopy, X-ray single crystal diffraction, fluorescence spectroscopy and proton nuclear magnetic resonance spectroscopy. Heterocyclic thiones have the chemical active group -N (H) -C (= S) -, which can be interconverted with its thiol form at equilibrium. The two complexes were obtained by reacting AgCl or AgNO3 with triphenylphosphine in a mixed solution of methanol and dichloromethane containing 2-mercaptobenzothiazole (MBT). Each asymmetric unit of complex 1 contains two identical molecular structures, but they have different bond lengths and bond angles. Complex 2 is a simple mononuclear heteroleptic complex whose main structure connects free CH 3 OH and NO 3 - ions through hydrogen bonding. The red shifts of the emission peaks of complexes 1 and 2 originate from π-π * transitions in the ligands.
