The Cu(II)-phenylhydrazine complex was synthesized and characterized by ultraviolet-visible spectroscopy, atomic absorption spectroscopy, thermogravimetry/differential scanning calorimetry, molar conductivity, infrared spectroscopy and magnetic susceptibility measurements. The metal complex was prepared through reaction of 1:4 mole ratio of CuSO 4 5H 2 O to phenylhydrazine ligand in methanol at room temperature for 15 minutes. The peak shifting in the electronic spectra to the smaller maximum wavelength than copper salt from 815 nm to 518 nm indicated the formation of the complex. The copper content in the complex was 13.93% which was according to the empirical formula of Cu(phenylhydrazine) 2 (SO 4 )(H 2 O)n (n= 4,5, or 6). Thermal analysis showed the release of five water molecules as hydrate and the electrical conductivity showed that the complex was nonelectrolyte. The complex was paramagnetic with an effective magnetic moment of 1.93 BM. The broadness band peak of the electronic spectra at 19531 cm −1 showed the d-d transition. The studies confirmed that the ligand is monodentate and the proposed formula of the complex was [Cu(phenylhydrazine) 2 (SO 4 )]·5H 2 O with square planar geometry.
