2-氨基苯并噻唑合硝酸银(Ⅰ)的合成、晶体结构及抑菌活性
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=2.225 Mg/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,NO3-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5.0×10-1~6.25×10-2 g/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。

Synthesis,Crystal Structure and Antibacterial Activity of 2-Aminobenzothiazole Silver(Ⅰ) Nitrate
Abstract:
A one-dimensional coordination polymer of Ag(Ⅰ) with 2-aminobenzothiazole,[Ag(C7H6N2S)(NO3)]∞(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,C7H6AgN3O3S,Mr=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,Dc=(2.225 Mg/m3),V=0.955 4(2) nm3,F(000)=624 and R1=0.036 2,wR2=0.070 2(I>2σ(I)).In compound 1,the 2-aminobenzothiazole coordinates to silver (Ⅰ) via its thiazole N atoms,and NO3- 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).
