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.
