Abstract:
Three solid complexes of Ni (II), Cu (II) and Zn (II) nitrates with norfloxacin, having the composition of [Ni (NFA)2 (NO3)] NO3.2H2O, [Ca (NFA)2] (NO3)2.H2O, [Zn (NFA)2 (NO3)] NO3.2H2O, have been synthesized in aqueous solvent. All the isolated complexes have been characterized by elemental analysis, IR spectra, thermogravimetric analysis and molar conductance in methanol. The results show that [Ni (Ni (NFA)2) (NO3)] NO3.2H2O, [Zn (NFA)2 (NO3)] NO3.2H2O 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 is non-electrolyte in methanol, the coordination number is 4. Norfloxacin molecules with inner salt types are all bidenlate ligands.

02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
