Polyhedron chemistry

WebWhat is the coordination polyhedron? The term ‘coordination polyhedron’ describes ligands’ geometric pattern or spatial arrangement directly linked to the centre atom or an ion. The most frequent coordination polyhedra are tetrahedral, octahedral, and square planar geometries. For example: The geometry of [Ni(CO)4] is tetrahedral Webincluding the properties of polyhedra, the nature and symmetry of repeating patterns, and the ways in which spheres, of the same or different sizes, can be packed together. In Part II the structural chemistry of the elements is described systematically, arranged according to the groups of the Periodic Table.
