摘要
合成了以2氨基苯并噻唑为配体的一维银(Ⅰ)配位聚合物[Ag(C7H6N2S)(NO3)]∞(1),并用元素分析、红外光谱及荧光光谱对其进行了表征。单晶X射线衍射结构分析表明,该化合物属单斜晶系,分子式为C7H6AgN3O3S,Mr=320.08,空间群为P2(1)/c,其晶胞参数为a=0.6834(1)nm,b=1.5416(2)nm,c=0.9069(1)nm,β=90.05(1)°,Z=4,Dc=2.225Mg/m3,V=0.9554(2)nm3,F(000)=624,R1=0.0362,wR2=0.0702(I>2σ(I))。在化合物1中2氨基苯并噻唑通过噻唑N与Ag(Ⅰ)配位,NO-3利用2个O原子桥连相临的Ag(Ⅰ)形成一维链状结构。抑菌活性实验表明,在5.0×10-1～6.25×10-2g/mL质量浓度范围内(DMSO为溶剂)配体和配合物对金黄色葡萄球菌、大肠杆菌、白色念珠菌都表现出了较好的抑菌活性。
A one-dimensional coordination polymer of Ag(Ⅰ) with 2-aminobenzothiazole, \[Ag(C_(7)H_(6)-N_(2)S)(NO_(3))\]_(∞)(1) was synthesized and characterized by means of elemental analysis, IR spectrum and fluorescence spectrum. Its crystal structure was determined by virture of X-ray single crystal diffraction method. The title compound, C_(7)H_(6)AgN_(3)O_(3)S, M_(r)=320.08, crystallized in the monoclinic system with space group P2(1)/c, a=0.683 4(1), b=1.541 6(2), c=0.906 9(1) nm, β=90.05(1)°, Z=4, D_(c)=(2.225 Mg/m^3), V=0.955 4(2) nm^(3), F(000)=624 and R_(1)=0.036 2, wR_(2)=0.070 2(I>2σ(I)). In compound 1, the (2-aminobenzothiazole) coordinates to silver(Ⅰ) via its thiazole N atoms, and NO^-_(3) bridges the adjacent (silver(Ⅰ)) via its′ two O atoms to form a one-dimensional chain structure. The antibacterial activity test result shows that the ligand and complex possess strong inhibition activity to Staphylococcus aureus, escherichia coli, Candida albicans in the concentration range of 5.0×10^(-1)~6.25×10^(-2) g/mL(DMSO as solvent).
