2,2′-Ethylenebis(1,3-dithiane) as a polydentate μ2-, μ4- and μ5-assembling ligand for the construction of sulphur-rich Cu(<scp>i</scp>), Hg(<scp>ii</scp>) and heterometallic Cu(<scp>i</scp>)/Hg(<scp>ii</scp>) coordination polymers featuring uncommon network architectures

The coordination chemistry of the polydentate thiaheterocycle 2,2′-ethylenebis(1,3-dithiane) L1 towards CuX and HgX2 salts was investigated using different metal-to-ligand ratios.
