Supramolecular structures constructed from three novel rare earth metal complexes

Abstract

Three rare earth metal supramolecular complexes, {[Tb(L 2 ) 4 ](ClO 4have 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.
