Description:
Four complexes based on a benzimidazole-thioether derivative ligand 2-[(4-pyridine)sulfydryl]-ethyl-1H-benzimidazole (pteHb), namely, {[CdCl 2 (pteHb) 2 ] 2 · 2DMF} n ( 1 ), [CdI 2 (pteHb)] 2 ( 2 ), {[CoCl 2 (pteHb)] 2 · DMF} ( 3 ), and {[ZnCl 2 (pteHb)] 2 · DMF} ( 4 ), were prepared under solvothermal and solvent evaporation conditions. X-ray diffraction analysis reveals that the Cl – ions of complex 1 act as μ 2 bridge to connect the Cd II ions resulting in a dinuclear unit. The units are bridged by the ligand pteHb to give a 1D double-looped chain. Complexes 2 – 4 are dinuclear and further assembled into a 3D supramolecular architecture via π–π interactions, hydrogen bonding interactions, and intermolecular forces. Complexes 1 – 4 were characterized by elemental analyses and IR spectroscopy. Furthermore, solid-state luminescent properties of complexes 1 , 4 , and ligand pteHb were also investigated.
