| description | The asymmetric unit of the title compound, [Cu2Tb(C7H3NO4)3(C12H8N2)4]NO3·4H2O, consists of one-half of the C2-symmetric trinuclear coordination cation, one-half of the C2-symmetric nitrate anion and two water molecules. In the coordination cation, the CuII atom is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from a bridging–chelating carboxylate group of the pyridine-2,6-dicarboxylate anion, completing a distorted N4O2 octahedral coordination environment. The TbIII atom, located on a twofold rotation axis, is nine-coordinated by three tridentate pyridine-2,6-dicarboxylate anions forming an N3O6 donor set. The intramolecular Cu...Tb distance of 5.0592 (11) Å indicates weak interactions between the CuII and TbIII atoms. The coordination cations, nitrate anions and water molecules are connected via O—H...O hydrogen bonds into layers parallel to the (001) plane. Moreover, there are extensive π–π stacking interactions [centroid–centroid distances = 4.332 (7) and 3.878 (5) Å] between the phenanthroline ligands and between phenanthroline and pyridine-2,6-dicarboxylate ligands. |
