📊
Key Findings & Data:Compounds were obtained in a three dimensional form with different pH values under subcritical water conditions.
💡
Conclusion & Impact:Their thermal stability, luminescence and electrical conductivity properties were investigated in the solid state.
Hydrothermal reactions of lanthanide(III) salt with 2,3-pyrazinedicarboxylic (2,3-pzdc) acid yielded the coordination polymers [La2(2,3-pzdc)3(H2O)]n.3nH2O (1) and [La2(2,3-pzdc)3(H2O)]n.2nH2O (2). Compounds were obtained in a three dimensional form with different pH values under subcritical water conditions. The structures had variable coordination numbers. In addition, pH values play an important role in the structural chemistry of these materials. Different characterization techniques (Elemental analysis, FT-IR, ICP-OES, TG/DTA, FESEM, PXRD, BET and single crystal X-ray) were carried out to confirm crystallinity, porosity, purity and chemical composition of the coordination polymers. Crystal structures of the polymers were examined in detail. Their thermal stability, luminescence and electrical conductivity properties were investigated in the solid state.
