Preparation, crystal structure and luminescent properties of the 3-D netlike supramolecular lanthanide picrate complexes with 2,2′-[1,2-phenylenebis(oxy)]bis(N-benzylacetamide)

Solid complexes of lanthanide picrates with a new podand-type ligand, 2,2′-[(1,2-phenylene)bis(oxy)]bis(N-benzylacetamide) (L) have been prepared. The crystal structure of NdL(Pic)3 is 3-D supramolecular structure formed by the intermolecular hydrogen bonds. The luminescent properties of the Eu(III) complex are described.
