    • Abstract


      Three rare earth metal supramolecular complexes,{[Tb(𝐿2)4](ClO4)3·2H2O(1), [Eu(𝐿2)2(H2O)5] (ClO4)3(2) and [Gd(NO3)3(𝐿2)2]·2CH3CH2OH(3) ( 𝐿2 = 3-Dimethylamino-1-pyridin-2-yl-propenone), have been synthesized and characterized by elemental analysis, IR and single crystal X-ray diffraction. The crystal structure analysis reveals that the coordination numbers of three complexes (1–3) are 8, 9 and 10, respectively. Three complexes assembled into 3D frameworks based on C-H⋯O, O-H⋯O hydrogen bond linkages.
