Preparation and characterization of some silicon (iv)‎ complexes

Abstract EN

Silicon (IV) complexes containing mixed ligands : Shiff-bases (AH) {derived from 2- or 3-amino-pyridine with 2-hydroxy- or 3-me- thoxy- or 2-hydroxy-3-methoxy-benzaldehyde }and benzalde- hyde semicarbazone (BSCH), have been prepared.

The resulted complexes have been characterized by elemental analysis, molar conductance values, infrared and electronic spectral data.

Complexes of the type [Si (BSCH) 2 (AH) ] Cl4, [Si (BSC) 2 (AnH)] Cl2 and [Si (BSC) 2 (A)] Cl (where n = 2 or 3, A = deprotonated Schiff-base ligands , BSC = deprotonated semicarbazone) have been proposed in neutral and basic medium, respectively.
