Conference paper


The equilibrium configuration of a set of 4 or 6 point charges about an isotropic attracting center is a regular tetrahedron or octahedron, respectively. In many determinations of crystal structures of compounds containing co — ordination complexes exhibiting coordination numbers 4 and 6, the coordination polyhedra are found to be more or less distorted from these regular configurations. There are many factors which may influence these distortions: differing sizes of the ligand atoms; differing“bonding strength” of the ligand atoms; steric effects of other atoms bonded to the ligand atoms; crystal packing effects; hydrogen bonding; Jahn-Teller or other crystal field effects
