Crystal Structure of the Neodymium Picrate Complex with a Novel Amide Type Tripodal Ligand

A solid complex of neodymium picrate with a novel amide-type tripodal ligand, 2,2′,2″-nitrilotris(3′-pyridinyl-methylaminoformylphenoxyl)triethylamine (L), has been prepared. An X-ray single-crystal diffraction analysis indicates that this complex was crystallized in the trigonal system, space group R3c with parameters a = b = 15.430(7)A, c = 112.448(7)A, α = β = 90.00°, γ = 120.00°, V = 23187(2)A3, Z = 6. The structure was refined to a final R1 of 0.0463. The coordination number around Nd(III) was nine, and the geometry of Nd(III) is a distorted tricapped trigonal prism. In the structure of the title complex, a 2D supramolecular network is formed by hydrogen bonds interactions.
