Abstract
The title compound, [Cd(S2O3)(C16H16N2)(H2O)]n, presents a polymeric one-dimensional structure running along the P21/c glide direction, with elementary units defined by six-coordinate CdII atoms bonded to three symmetry-related thiosulfate groups, a bidentate tetramethylphenanthroline ligand and one aqua ligand. The bridging thiosulfates bind metal centers through two different sequences, viz. Cd–S–Cd′ and Cd′–S′–S′–O′–Cd, defining a closed six-membered ring. Individual chains are held together via π–π interactions to generate two-dimensional networks parallel to the (100) plane. These, in turn, are connected by much weaker van der Waals interactions.
