Abstract: | In polymeric {Eu(pzdc)(NO3)(phen)(H2O)]·H2O}n pzdc is 2,3‐pyrazinedicarboxylate (C6H2O4) and phen is 1,10‐phenanthroline (C12H8N2)], each europium(III) ion is coordinated by seven O atoms (from three pzdc anions, a nitrate anion and a water molecule) and the two N atoms of the phen ligand, resulting in a nine‐coordinated europium(III) center with a distorted monocapped square‐antiprismatic coordination polyhedron. Four pzdc anions bridge four europium(III) ions, forming a parallelogram unit, the four vertices of which are occupied by the four pzdc anions. Moreover, each parallelogram unit links six other adjacent parallelogram units, forming a two‐dimensional network with disordered lattice water molecules. |
