| Abstract: | Europium(III) compound with 2‐oxopropionic acid salicyloyl hydrazone (C10H10N2O4, H3L) and 1,10‐phenanthroline (C12H8N2, phen) has been prepared. A yellow prismatic crystal of the compound was obtained, and the molecule crystallized in the triclinic space group P‐1. There are two 9‐coordinated complex molecules in every structure unit, where every Eu atom is coordinated by three water molecules and two tridentate C10H10N2O4 ligands, forming two stable pentacycles. The coordination polyhedron around Eu3+ was described as a single cap square antiprism. In the crystal cell, there are one free 1,10‐phenanthroline and four water molecules. The thermal decomposition of the compound and its kinetics were studied by non‐isothermal thermogravimetry. The Kissinger′s method and Ozawa′s method were used to calculate the activation energy value of the first‐step decomposition. The stages of the decompositions were identified by TG‐DTG‐DSC curve. The non‐isothermal kinetic data were analyzed by means of integral and differential methods. The possible reaction mechanism and the kinetic equations were investigated by comparing the kinetic parameters. |
