Preparation and Characterization of New Silicon Mixed Ligand Complexes

Abstract

Silicon (IV) complexes with mixed ligands: 2-fluorobenzaldehydesemi- carbazone and Schiff-bases (derived from 2- or 3-aminopyridine with 2-hydroxy or 3-methoxy or 2–hydroxy-3-methoxybenzaldehyde) have been prepared. Complexes of the type [Si(FSCH)2(LH)]Cl4 and [Si(FSC)2(LnH)]Cl2 or [Si(FSC)2(L)]Cl (where FSCH = 2-fluorobenzaldehydesemicarbazone , FSC = deprotonated semi- carbazone ligand , LH = Schiff-base ligands) have been proposed in neutral and basic medium , respectively . The resulted complexes have been characterized by physical and chemical methods .
