| Abstract: | Under the hydrothermal conditions, Nd(NO3)3·6H2O reacted with pyridine‐2,4‐dicarboxylic acid (2,4‐pydcH2) to give a 2D co‐ordination polymer with the empirical formula of C16H18N2Nd2O18×H2O ( 1 ). Pr(NO3)3·6H2O also reacted with 2,4‐pydcH2 to give another 2D coordination polymer (C8H9NO9Pr)2·H2O ( 2 ). The structure of both polymers have been determined by X‐ray diffraction. X‐ray structural analyses show that both polymers contain bridging oxalate (C2O42?) ligands, which might have been formed by the coupling of two CO2?× radicals, released from pydc2? ligands. |
