A new flexible bis-bidentate N2S2 Schiff base ligand (2,4-Cl-ba)2dapte = N,Nʹ-bis-(2,4-dichlorobenzaldehyde)-1,2-di(o-iminophenylthio)ethane and its copper(I) coordination polymer [Cu2(μ-I)2(μ-(2,4-Cl-ba)2dapte)]n, were synthesized and characterized by CHN elemental analysis, FT-IR and UV-Vis spectroscopy and single-crystal X-ray diffraction. The molecule of (2,4-Cl-ba)2dapte adopts a trans conformation of the 1,2-di(o-iminophenylthio)ethane unit. The (2,4-Cl-ba)2dapte acts as a bis-bidentate ligand with two iminic nitrogen and two sulfur atoms, coordinating to copper(I) ions in an anti-form leading to the dinuclear Cu2(μ-(2,4-Cl-ba)2dapte) groups. These groups are then bridged by two iodide anions to form a copper(I) coordination polymer [Cu2(μ-I)2(μ-(2,4-Cl-ba)2dapte)]n. The coordination geometry around the copper(I) ions is a distorted tetrahedron. Finally, a nano-sized form of the copper(I) coordination polymer [Cu2(μ-I)2(μ-(2,4-Cl-ba)2dapte)]n was prepared by an ultrasonic bath assisted process and characterized by elemental analysis, FT-IR and SEM.
