摘 要：The self-assembled formation of a one-dimensional lanthanum salicylald imine coordination polymer was proved by the X-ray diffraction analysis of new l anthanum（Ⅲ） nitrate complex containing N,N’-bis（salicylidene）-1,5-pentanediami ne ligand（H2L） . It was obtained in situ in a one-step,metal-templated condensa tion of salicylaldehyde with 1,5-pentanediamine（cadaverine,biogenic polyamine） and characterized by microanalysis and spectroscopic（IR,ESI-MS,UV-Vis,and 1 H NMR） data. The [La（NO3） 3（μ-H2L） 2]∞ complex displayed 10-coordinate distorted bicapped dodecahedron geometry with unusual coordination pattern of undeprotonat ed salicylaldimines which acted as μ-bridging ditopic ligands using exclusivel y the oxygens as donor atoms with the nitrogen atoms not being involved in the c oordination environment.
