One dimensional coordination polymers generated from Cd(II) tri-tert-butoxysilanethiolates and flexible aliphatic diamines

摘要

This work concerns the coordination chemistry of cadmium(II) tri-tert-butoxysilanethiolates in the presence of aliphatic diamines. Reactions of the binuclear [Cd{SSi(OtBu)_3}_2]_2 with the respective diamines yielded five new neutral one-dimensional coordination polymers, [Cd{SSi(OtBu)_3}_2(μ-C_4H _(12)N_2)(CH_3OH)]_n (1), [Cd{SSi(OtBu)_3}_2(μ-C_5H_(14)N _2)(CH_3OH)]_n (2), [Cd{SSi(OtBu) _3}_2(μ-C_6H_(16)N_2)(CH _3OH)]_n (3), [Cd{SSi(OtBu)_3}_2(μ- C_7H_(18)N_2)]_n (4) and [Cd{SSi(OtBu)_3}_2(μ-C_8H_(20)N _2)]_n (5), which adopt different spatial chain topologies. The new polymers were fully characterized by X-ray single-crystal diffraction, elemental analysis and IR spectroscopy. The thermal stabilities of complexes (1), (3) and (4) complexes were studied by thermogravimetry (TG, DTG).
