摘要

Abstract

New samarium complex of 5-phenyl-2,2'-bipyridine with the diethylenetriaminotetraacetic acid (DTTA) residue in the C6 position, [(L2)Sm2Na5(H2О)9(C2O4)]n (I), is synthesized. The structure of complex I is studied by XRD (CIF file CCDC no. 2217968). The complex in the crystal is found to be a one-dimensional coordination polymer, and the 2,2'-bipyridine fragments do not chelate the Sm3+ cation. The complex is characterized by a luminescence response to the addition of an excess of zinc cations.
