Synthesis of Fe(II), Mn(II), Zn(II), and Ru(II) complexes Fe(II), Mn(II) and Zn(II) complexes were obtained accor- ding to a general procedure: The metal salts (1.00 mmol, 0.14 g for FeCl2∙H2O; 0.19 g for MnCl2∙4H2O; 0.17 g for ZnCl2∙ 2H2O) were dissolved in ethanol and stirred under reflux for 10 min. Followed by the addition of the Schiff base (0.80 g, 2.33 mmol for Fe(II) and Mn(II) complex; and 1.60 g, 4.66 mmol for Zn(II) complex) in ethanol and reaction mixture stirred upon heating for 24 h.	cache/eurjchem-1671.pdf	txt/eurjchem-1671.txt
