چکیده انگلیسی
Manganese(II) complex [Mn(phen)(H2O)4]·SO4·2H2O has been synthesized in aqueous methanol medium. The complex crystal was directly obtained from reaction of MnSO4·H2O in water with a mixture of methanol solution of disalicyaldehyde oxaloyldihydrazone and 1,10-phenanthroline. Its structure has been established by X-ray crystallography. It has also been characterized by thermogravimetry, TEM, magnetic moment, UV-visible, EPR and IR spectra. The complex is normal paramagnetic and shows a weak d-d band at 420â¯nm due to 6A1g (F)ââ¯4T2g (G) transition and strong charge transfer bands. The EPR spectrum of the complex is indicative of decrease of metal-metal interaction with decrease in temperature. IR spectra of the complex is consistent with the coordination of 1,10-phenanthroline to the manganese(II) centre.
