Syntheses, Structures, and Luminescence of Two Complexes

Abstract

Two new complexes, namely {[La(L3)3(2,2′-bipy)]n·H2O} (1), and [Zn(L3)2(4,4′-bipy)]n (2) (HL3 = o-hydroxy phenylpropionic acid, 2,2′-bipy = 2,2′-bipyridine and 4,4′-bipy = 4,4′-bipyridine), have been synthesized and structurally characterized by single-crystal diffraction analysis. 1 has a dinuclear motif, which is further linked into 2D layer via the hydrogen bond interactions. 2 shows 1D covalent zigzag chain constructed by 4,4′-bipy ligands. Furthermore, the luminescent properties of 1–2 show the mild emissive power and feature.
