摘　　要：选用吡唑-3-甲酸为主配体,通过溶剂热法合成出两种配合物{[Ag3(3-PCA)3][Ag(DMAP)2]3}·10H2O(1)和[Cu2(3-PCA)2(DMAP)4]·2H2O(2)(3-PCA=pyrazole-3-carboxylic acid,DMAP=4-Dimethylaminopyridine).用X射线单晶衍射仪测定了它们的晶体结构,并进行了红外表征.结果显示,配合物(1)为单斜晶系,空间群为Pc,晶胞参数为a=0.9409(8)nm,b=1.3411(8)nm,c=2.8699(2)nm,Z=2,V=3.6215(5)nm^3;配合物(2)属于三斜晶系,空间群为Pī,晶胞参数为a=0.8999(14)nm,b=1.0870(18)nm,c=1.1050(17)nm,α=78.426(14)°,β=68.732(15)°,γ=87.237(13)°,Z=1,V=0.9865(3)nm 3.对配合物(1)进行了固态荧光测试,结果表明其具有荧光性质;对配合物(2)进行了生物活性研究,结果表明该配合物可与BSA相互作用.Using pyrazole-3-carboxylic acid as the main ligand,two complexes{[Ag3(3-PCA)3][Ag(DMAP)2]3}·10H2O(1)and[Cu2(3-PCA)2(DMAP)4]·2H2O(2)(3-PCA=pyrazole-3-carboxylic acid,DMAP=4-Dimethylaminopyridine)were synthesized by solvothermal reaction.Their crystal structures were determined by using x-ray single crystal diffractometer,and characterized by IR spectroscopy.The results show that complex(1)belongs to monoclinic,the space group Pc,a=0.9409(8)nm,b=1.3411(8)nm,c=2.8699(2)nm,Z=2,V=3.6215(5)nm^3,and complex(2)belongs to the triclinic system,space group Pī,a=0.8999(14)nm,b=1.0870(18)nm,c=1.1050(17)nm,α=78.426(14)°,β=68.732(15)°,γ=87.237(13)°,Z=1,V=0.9865(3)nm 3.The solid-state fluorescence test of the complex(1)confirmed its fluorescence properties;The interaction of complex(2)with BSA was studied.
