The X-ray analysis reveals that the title compound, bis(μ-O-ethyl dithiocarbonato)-1κS,1:2κ²S';2κS,1:2κ²S'-bis<(O-ethyl dithiocarbonato-κ²S,S')cadmium(II)>, , is a dimer of distorted octahedral Cd ions each coordinated to six S atoms: one non-bridging S atom of the thiourea ligand at a distance of 2.641 (1) Angstroem, four non-bridging S atoms of the chelating/chelating-bridging xanthato (O-ethyl dithiocarbonato) ligands at distances of 2.606 (2)-2.765 (1) Angstroem, and one bridging S atom of the chelating-bridging xanthato ligand at a much longer distance of 2.831 (2) Angstroem.The shortest metal-sulfur distances involve the S atoms of one of the chelating moieties, while the S atoms of the chelating-bridging moiety form one of the shorter and longest '2.831 Angstroem' metal-sulfur distances.The other 'short' bond is subtended to an S atom of a symmetry-related bridging-chelating ligand.Cd, S(2), S(2ⁱ) and Cdⁱ are coplanar .
