Syntheses, Structures and Properties of Pyrazole-3-carboxylic Acid Complexes

  • 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)3Ag(DMAP)23·10H2O(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)nm3;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)nm3.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.

     

    Abstract: Using pyrazole-3-carboxylic acid as the main ligand, two complexes Ag3(3-PCA)3 Ag(DMAP)2 3·10H2O (1) andCu2(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=3.621 5(5) nm3, 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) nm3. The solid-state fluorescence test of the complex (1) confirmed its fluorescence properties; The interaction of complex (2) with BSA was studied.
