Synthesis, characterization and antibacterial test of Tetrakis(3-Aminophenol) Copper(II)Nitrate Hexahydrate

The purposes of this research were to synthesize and characterize of copper(II) with 3-aminophenol and determine its antibacterial activity. The complex was synthesized by refluxing a mixture of metal solution and ligand sulition in 1:4 mole ratio for one hour in methanol. The percentage of copper was 8.88% determined by Atomic Absorption Spectroscopy (AAS) therefore the predicted formula was Cu(3-aminophenol)4(NO3)2(H2O)6. Molar conductivity of the complex was measured by conductivity meter corresponding to 1:2 electrolyte. The thermal analysis of the formed complex indicated that the complex containing six water molecules as hydrates. The magnetic susceptibility measurement showed that the complexes was paramagnetic with μeff= 1.88 BM. Electronic spectra of the formed complex appeared at one transition peak on λ= 446 nm. The infrared spectra of the complex showed a shift of (N-H) band and (N-H) stretch group absorption in 3230 and 1497 cm−1 compared to 3-aminophenol at 3362 and 1594 cm−1. This fact indicated that the (N-H) functional groups were coordinated to the central metal ion. The plausible formula of the complex was [Cu(3-aminophenol)4](NO3)2.6H2O with a square planar structure. The complex showed no antibacterial activity againts Gram-positive bacteria (S. aureus, S. epidermidis) and Gramnegative bacteria (E. coli, P. aeruginosa).
