Abstract/Summary

The synthesis and characterization of three zinc(II) polymers, [(μ-OAc)3Zn2L1]n·0.5nH2O (1), [(μ-OAc)3Zn2L2]n (2), [(μ-OAc)3Zn2L3]n (3), using three tridentate ligands, HL1 {2-(((2-(diethylamino)ethyl)amino)methyl)phenol}, HL2 {4-chloro-2-(((3-(dimethylamino)propyl)amino)methyl)phenol} and HL3 {4-bromo-2-(((3-(dimethylamino)propyl)amino)methyl)phenol}, have been reported in this manuscript. The structures were confirmed by SC-XRD analysis. The DFT study analyzes the cooperative roles of bridging acetate co-ligands and NH⋯O hydrogen bonds. A structural survey of the Cambridge Structural Database (CSD) reveals that polymeric complexes derived from reduced bicompartmental Schiff base ligands are rare, emphasizing the unique structural features and supramolecular assembly observed in the present work.
