Single crystal x-ray studies of w- halogeno ethylenediamine diethylenetriamine cobalt (111) complexes

Abstract

In this thesis the crystal and molecular structure of w-Co(en)(dien)Cl Cl2-1/2 H2O (where en = ethylenediamine and dien = diethylenetriamine) has been determined by single crystal X-ray diffraction methods, thus elucidating the configuration of the w-isomer. The structure was solved using Patterson and Difference Fourier syntheses and refinement was carried out using a full matrix least squares refinement process. The space group and unit cell parameters of the related compounds W-co(en)(dien) I I2 and :w-Co(en)(dien)Cl ZnCl4 have been determined and the indexed X-ray powder diffraction patterns of all three compounds are also given. Finally a discussion of the experimental errors arising in X-ray crystal structure determinations is also included.
