Binuclear Co(II), Zn(II) and Cd(II) tri-tert-butoxysilanethiolates. Synthesis, crystal structure and spectroscopic studies
چکیده انگلیسی

A series of Co(II), Zn(II) and Cd(II) complexes have been synthesized in reaction of respective metal tri-tert-butoxysilanethiolates with pyrazine 1 and 2 and 1,2-bis(2-pyridyl)ethylene 3–5. All compounds have been characterized by single-crystal X-ray structure determination, elemental analysis, FT-IR and thermogravimetry. Obtained complexes are bimetallic with the formula of [M{SSi(OtBu)3}2(μ-L)]2 and metal ions bridged by N,N′-spacer. The penta-coordinated spheres of the metallic atoms are completed by tri-tert-butoxysilanethiolate residue playing the role of O,S-chelating ligand. Luminescent properties of 1, 2, 4 and 5 complexes have also been investigated in solid state.

Five binuclear Co(II), Cd(II) and Zn(II) silanethiolates have been synthesized. Single-crystal structures of complexes have been calculated using XRS. Metal ions are bridged by pz and bpe. Complexes 1, 2, 4 and 5 display luminescent properties.Figure optionsDownload as PowerPoint slide
