1D Coordination Polymer of Mg with Kojic Acid: Synthesis, Structure, and Thermal Behavior

Abstract

Coordination compound [Mg(HKoj–)2]n is synthesized by the reaction of kojic acid (H2Koj) with magnesium acetate in an aqueous solution. The empirical formula of the synthesized compound is determined from the elemental and thermogravimetric analyses data. The thermal oxidative stability of magnesium kojate is studied by simultaneous thermal analysis in air. The molecular structure of the complex is discussed using spectral methods (NMR and IR spectroscopy) and studied in detail using X-ray diffraction (XRD) analysis (CIF file CCDC no. 2513260). Magnesium kojate is a coordination polymer with the chelate environment of the metal cation. The compound crystallizes in the triclinic symmetry group.
