A ring-like coordination structure constructed by Cu(II) and bis(2-(pyridin-2-ylthio)ethyl)ether ligand

The reaction of bis(2-(pyridin-2-ylthio)ethyl)ether (L) with CuCl2 in CH3OH/CHCl3 solution gives a novel 24-membered ring-like coordination structure which has been characterized by elemental analysis, IR, and X-ray single-crystal diffraction. The X-ray diffraction analysis reveals that [Cu2L2Cl4] crystallizes in the triclinic, space group . The ring-like structure is consisted of two ligands with two copper ions coordinated to the pyridyl nitrogen atoms from two ligands respectively. The largest diameters of the planarshaped dinuclear ring are about 12.7 . The adjacent ring-like units are linked via C-HaEuro broken vertical bar O hydrogen bonds to generate an infinite linear chain, which are further linked by C-HaEuro broken vertical bar Cl hydrogen bonds and weak intermolecular interactions to form a three-dimensional network.
