This dissertation in concerned with the stereochemical problem of pentaco-ordination. The early theoretical work of Pauling, Daudel and Bucher and Linnett gave conflicting predictions about the relative stabilities of the square pryramid and the trigonal bipyramid, and offered no explanation for the many distortions from these idealised geometries observed in pentaco-ordinate complexes. Due to the unsatisfactory description given by these rather simple theories alone, several workers have recently suggested other factors which they consider important in determining the relative stabilities of the possible geometries. They are: (a) valency-shell electron-pair repulsions; (b) crystal field stabilization energy; (c) steric requirements of the ligand; (d) packing requirements in the crystal. The crystal and molecular structures of four complexes have been analysed by X-ray diffraction techniques in order to gain further information about the relative importances of these factors in determining the stereochemistry of pentaco-ordinate complexes.
