Cadmium Nanoclusters with Phenylselenolato-and Phenyltellurolato Ligands: Synthesis and Structural Characterization of [Cd_17Se_4(SepH)_24(PPh_3)_4][Cd_8Se(SePh)_12Cl_4], [Cd(DMF)_6][CD_8Se(SePh)_12 Cl_4], [Cd_8Se(SePh)_14(PPh_3)_2], [Cd_8Se(SePh)_14

摘要

A method of synthesis for cadmium selenide and cadmium telluride clusters is proposed. PhSeSiMe_3 reacts with [CdCl_2(PPh_3)_2] to yield a series of cadmium selenide clusters depending on the kind of solvent used. The reaction of PhTeSiMe_3 with CdCl_2 and Ptt_3 yields a cadmium telluride cluster. Crystalline products Suitable for single-crystal X-ray analysis could be obtained. We describe the molecular structures of [Cd_17Se_4(SepH)_24(PPh_3)_4][Cd_8Se(SePh)_12Cl_4](1),[Cd(DMF)_6][CD_8Se(SePh)_12 Cl_4](2), [Cd_8Se(SePh)_14(PPh_3)_2] (3), [Cd_8Se(SePh)_14(DMF)_3] (4)and [Cd_8Te(TePh)_14 (Pet_3)_3] (5).
