Abstract

The zinc and magnesium Schiff-base complexes [ZnL(H₂O)(NO₃)]NO₃ (1) and [MgL(H₂O)₃] (NO₃)₂·H₂O (2) (L = Schiff base derived from 4-bromo-2-[(2-diethylaminoethyl)ethylaminomethyl]-6-formylphenol and glycine) have been prepared and structurally characterized. The reaction of 1 with Mg²⁺ has been studied in water, methanol and DMSO. Substitution of Zn by Mg²⁺ was observed in DMSO and methanol and the amount of Mg complex formed was found to be strongly dependent on the nature and concentration of the anions in solution: Cl^- and CH₃CO₂^- mediate conversion of 1 into 2, while ClO₄^-, NO₃^-, F^-, Br^-, I^- and SO₄^2- are ineffective.
