Some Maleate New Tin (IV) and Magnesium or Zinc Chloride Adduct and Derivative: Synthesis and Spectroscopic Study

Three new maleate compounds have been synthesized and studied by infrared, 25 Mg NMR (Nuclear Magnetic Resonance) Spectroscopy and UV (Ultraviolet)-visible spectroscopies.The suggested structures for the three complexes are discrete with NH-Cl hydrogen bonds.The maleate anion is monochelating (compound 1 and 2) and bichelating (compound 3).The environment tin (IV) and magnesium center are octahedral and the zinc center environment is tetrahedral.In all the suggested structures, when extra hydrogen bonds are considered, supramolecular architectures are obtained.
