| 摘 要： | Amide-type tripodal ligands have been used as ac-tive materials in ion-selective electrodes, ion recogni-tion and ion-transfer carrier, etc.,1-3 but their lanthanide complexes have not yet attracted much attention in spite of their high tendency to coordinate towards Ln(III) ions. The first three dimensional network of Eu(III) complex, which contains 1,1,1-tris{(2-benzylaminoformyl)- phenoxy]methyl}propane (the hexadentate ligand) and Eu(NO3)3 as building block, assembled by coordination …

| Abstract: | The La(III) complex with a new amide-type tripodal ligand, 2,2,2-nitrilotris{(2-benzylaminoformyl)- phenoxy]ethyl}amine (L), was synthesized and characterized by X-ray crystallographic analysis. Crystal data: C48H55.50LaN7O18.75, Mr=1169.40, monoclinic, space group, P21/n, a=1.0644(3) nm, b=2.3889(5) nm, c=2.1917(5) nm, b=90.65, V=5.573(2) nm3, Z=1, Dc=1.394 gcm-3, R1=0.0487, wR I>2s(I)]=0.1266. The results reveal that each La(III) ion binds to 9 oxygen atoms, three of which belong to carbonyl groups from three tripodal ligands and six to three bidentate nitrate groups and a two-dimensional sheet of 4.82 networks is assembled by metal-ligand coordination interaction. L, a heptadentate compound, merely acts as a tridentate bridging spacer due to its steric hindrance and links the La(III) ions as three-connected nodes. |
