Summary: | 碩士 === 國立交通大學 === 物理研究所 === 86 === This paper includes two parts. One is to determine the structure
of the single crystal of four Metal(Ⅱ) Complexes by X-ray
diffraction. The other is the method and process in the crystal
growth for the protein of CardiotoxinⅣ First: The four crystals
were provided by Prof. Chung-Sun Chung in the Chemistry
Department of NTHU. We determined the structure of the 4 single
crystals by X-ray diffraction. Of the four complexes, copper(Ⅱ)
ion is five coordinated with geometry of distorted trigonal
bipyramid structure in the first crystal. Copper(Ⅱ) ion has six
coordinations with distorted square bipyramid in the second
crystal. In the third, nickel(Ⅱ) ion has six coordinations with
four N atoms equatorial and N atoms of the isothiocyanate groups
axial, the same geometry as the second crystal. Nickel(Ⅱ) ion
is four-coordinate with four nitrogen atoms in the macrocyclic
plane in the last crystal.Second: The purified material of
CardiotoxinⅣwas provided by Prof. C.C. Yang in the Department
of Life Science of NTHU. We used hanging drop of vapor diffusion
method to grow protein of crystal. We tried to screen the best
condition for the crystallization of CadiotoxinⅣ from 48
conditions.
