| Research Abstract |
As zinc family metals have a d^<10> electronic structure, we cannot have many data for detection and/or analysis of the metal binding motifs and metal ions. In order to get more insight on the basic coordination chemistry of zinc family proteins, we explored to synthesize the zinc family thiolato complexes, two-coordinate thiolato complexes, [M(SR)_2]M_n(M=Zn(II), Cd(II), and Hg(II)), three-coordinate thiolato complexes, [M(SR)_3]_n, four-coordinate thiolato complexes ; M(SR)[HB(3,5-iPr_2pz)_3]. Moreover, halogeno complexes, [M(X){HB(3,5-iPr_2pz)_3}], were also synthesized. These complexes were characterized by X-ray analysis for their structural information, including M-S distances and angles, and by Far-IR and FT-Raman spectroscopy for M-S stretching energy, and by UV spectroscopy for CT energy. This report was described the relationship between the coordination structure as well as M-X distance and their physicochemical properties in detail.
