Abstract
Structural characterization of [S(CH(2)CH(2)pz(Me2))(2)]ZnCl2 by X-ray diff raction demonstrates that the potentially tridentate [NNS] donor ligand S(C H(2)CH(2)pz(Me2))(2) does not coordinate via sulfur, but only binds through the pyrazolyl groups. Furthermore, the ligand does not chelate, but prefer entially bridges two zinc centers, thereby resulting in a polymeric, helica l, structure. In contrast to the zinc system, the thioether functionality d oes bind to cadmium in related derivatives, [S(CH(2)CH(2)pz(Me2))(2)]CdI2 a nd [S(CH(2)CH(2)pz(Me2))(2)]Cd(NO3)(2).
