This work focuses on the preparation and characterization of new copper(I) Schiff base complexes, [Cu(LC)I]n (LC = N, N-bis(4-chlorobenzylidene)ethane-1,2-diamine), [Cu(LB)I]n (LB = N, N-bis(4-bromobenzylidene)ethane-1,2-diamine), and [Cu(LN)I]n (LN = N, N-bis(4-nitrobenzylidene)ethane-1,2-diamine). A one-dimensional polymeric structure of [Cu(LB)I]n was confirmed through single-crystal X-ray diffraction (SC-XRD) analysis. The copper atom is coordinated in a distorted tetrahedral fashion by a Schiff base ligand and two iodide ions. Hirshfeld surface analysis is done to explore intermolecular interactions in terms of interatomic contacts. Electrochemical studies revealed that these Cu complexes undergo quasi-reversible oxidation (involving CuII/CuI redox couple) under experimental conditions. Also, the results of cyclic voltammetry (CV) investigations disclosed that the redox reaction of [Cu(LB)I]n and [Cu(LN)I]n are more reversible than [Cu(LC)I]n.
