Abstract- Mn(II) complex compounds were synthesized from the reaction of MnCl2.4H2O with the Schiff base ligand 2-methoxy-6((4-methoxyphenilimino)methyl) phenol, C15H15NO3, by sonication method. The synthesized product has a yield of 83,24%, brownish-red solid, melting point of ~233 0C. UV-Vis spectrum has optimum absorption at 270, 277, 335, and 615 nm. FT-IR results show absorption bands 533 cm-1 and 498 cm-1 which indicated M-O and M-N bonds. The 1H-NMR spectrum shows one ligand indicating the presence of 5 signals with 19 protons. Powder X-ray diffraction of the Mn(II) complex shows (intensity 492 (a.u)) at 140 diffraction angle was observed.
