Design of coordination polymers based on combinations of 1,2-diphenylethane-1,2-diyl diisonicotinate with Cu(ii), Zn(ii), Cd(ii) and Co(ii)

Abstract

Five new supramolecular coordination polymers (L-Cu(acac)₂, L-Cu(hfac)₂, L-ZnCl₂, L-CdI₂ and L-CoCl₂) based on the use of the flexible organic ligand L (1,2-diphenylethane-1,2-diyl diisonicotinate) combined with Cu(acac)₂, Cu(hfac)₂, ZnCl₂, CdI₂ or CoCl₂ metallaligands, were synthesized and structurally characterized by single-crystal X-ray diffraction. They represent the first reported coordination polymers based on this ligand presenting ester junctions. X-ray diffraction analysis revealed the structure and the dimensionality of these coordination polymers as well as their packing in the crystal that depends on the conformation adopted by the ligand L and the nature of the used metallic salts.
