Three New Hydrogenosuccinate and Succinate AdductsComplexes: Synthesis and SpectroscopicStudy

One new hydrogenosuccinate and two succinate adduct and complex have been synthesized and studied by infrared, UV-Visible and NMR (Nuclear Magnetic Resonance Spectroscopy) 119 Sn spectroscopies.The suggested structure is discrete, the hydrogenosuccinate behaving as a monodentate ligand or only involved in hydrogen bonding, the environment around the magnesium centre being triangular (compound 3).The succiate anion is a monochelating ligand (compound 1 and 2).In all the suggested structures, when extra hydrogen bonds are considered, supramolecular architectures are obtained (compound 2 and 3).
