In the case of Co,Cu,Mn and iron just add them (Metal salt) with salen or salphen ligand using methanol as a solvent and i can get the schiff base product. but i am unable to get the product when i am using Ruthenium (RuCl3.xH2O). i have prepared Co(III) schiff bases also , in that the axial ligand is methanol(solvent). if it possible kindly help me to get the procedure for synthesis of Ru(II)/Ru(III)-schiff base complex using methanol as a solvent.
