Ni(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ)的硝酸盐与氟哌酸的固态配合物的合成与表征

Systhesis and Characterization of the Solid Complexes of Ni(Ⅱ)、Cu(Ⅱ) and Zn(Ⅱ) Nitrates with Norfloxacin

由氟哌酸与 Ni( )、Cu( )、Zn( )的硝酸盐合成了三个未见报道的固态配合物 ,并用元素分析、摩尔电导、红外光谱、热重分析表征了它们的组成和性质。

Three solid complexes of Ni(Ⅱ)、Cu(Ⅱ) an d Zn(Ⅱ) nitrates with norfloxacin,having the composition of [Ni(NFA ) 2(NO 3)]NO 3·2H 2O,[Ca(NFA) 2](NO 3) 2·H 2O,[Zn(NFA) 2(NO 3)]NO 3·2H 2O,have been synthesi ze d in aqueous solvent.All the isolated complexes have been characterized by eleme ntal analysis,IR spectra,thermogravimetric analysis and molar conductance in met hanol.The results show that [Ni(Ni(NFA) 2)(NO 3)]NO 3·2H 2O ,[Zn(NFA) 2(NO 3)]NO 3·2H 2O are 1∶1 tape electrolytes in methanol,their coordination numbers are all 6.The nitrates of inner boundary are all bidenlate ligands.The complex torming with copper nitrate and norfloxacin i s non-electrolyte in methanol,the coordination number is 4.Norfloxacin molecule s with inner salt types are all bidenlate ligands.
