| Abstract | ||
| Copper ( ІІ ) and oxovanadium( IV )chelating complexes of a tetra dentate ligands using acetazolamide (( N– [ 5 – ( amino sulfonyl ) – 1,3,4 – thiadiazol – 2 –yl ] acetamide )) and amoxicillin (( 6 – [[ amino ( 4 – hydroxy phenyl ) acetyl ] – amino ] – 3,3 – dimethyl –7 –oxo– 4 – thia –1 – aza bicyclo [ 3,2,0 ] heptane – 2– carboxylic acid )) drugs as a chelating agents have been prepared .Infrared , UV– visible techniques and molar conductivity measurements and solubility test were used to characterize and investigate the geometrical structure and nature of complexation in the new complexes .we obtained that Cu (II) complexes had ionic properties and dissolve in polar solvent but VO ( IV ) complexes had no ionic properties and dissolve in polar and non polar solvents . Dissociation constant ( Kd ) , molar conductivity in zero concentration (Λ 0) for all prepared complexes were obtained from molar conductivity measurements and from these we obtained that VO ( IV ) complexes had low value in molar conductivity and act as a weak electrolyte in DMSO but Cu ( II ) complexes had higher value than VO ( IV ) complexes . | ||
