Although coordination complexes are particularly important inthe chemistry of the transition metals, some main group elementsalso form complexes. Aluminum, tin, and lead, for example, formcomplexes such as the AlF63-, SnCl42-and PbI42- ions.

The new product is commonly known as the , or more officially, hexamminecopper(II). This equation is somewhat misleading, however, in that it implies the formation of a new complex where none existed before. In fact, since about 1895 it has been known that the ions of most transition metals dissolve in water to form complexes with water itself, so a better representation of the reaction of dissolved copper with ammonia would be
Transition-metal complexes have been characterized withcoordination numbers that range from 1 to 12, but the most commoncoordination numbers are 2, 4, and 6. Examples of complexes withthese coordination numbers are given in the table below.

where i is the equilibrium constant for the reaction in which the complex containing ligands is formed from the metal ion and ligands.
Werner assumed that transition-metal complexes had definiteshapes. According to his theory, the ligands in six-coordinatecobalt(III) complexes are oriented toward the corners of anoctahedron, as shown in the figure below.

Vladimir A. D’yakonov was born in 1980 in Yakutia, Siberia, Russia, graduated from the Ufa State Petroleum Technical University in Ufa, Bashkortostan, Russia (2002) with an honors diploma, and obtained his Candidate, Ph.D. (2005) and Doctor of Science, Chemistry (2012) degrees from the Institute of Petrochemistry and Catalysis of Russian Academy of Sciences under the guidance of the Correspondent member of RAS, Prof. Usein M. Dzhemilev. His research interests include metal complex catalysis in organic and organometallic synthesis, the development of new catalytic synthetic methods based on transformations of strained molecules and metallacarbocycles, and the elaboration of simple “one-pot” operations for the preparation of various carbo-, hetero-, and macrocyclic compounds.

Her research interests include metal complex catalysis in organic and organometallic synthesis, and the chemistry of spiro compounds.
Transition metal complexes in organic synthesis. Part 47
G. N. Lewis was the first to recognize that the reactionbetween a transition-metal ion and ligands to form a coordinationcomplex was analogous to the reaction between the H+and OH- ions to form water. The reaction between H+and OH- ions involves the donation of a pair ofelectrons from the OH- ion to the H+ ion toform a covalent bond.

Werner was able to show, in spite of considerable opposition, that transition metal complexes consist of a central ion surrounded by ligands in a square-planar, tetrahedral, or octahedral arrangement. This was an especially impressive accomplishment at a time long before X-ray diffraction and other methods had become available to observe structures directly. His basic method was to make inferences of the structures from a careful examination of the chemistry of these complexes and particularly the existence of structural isomers. For example, the existence of two different compounds AX4 having the same composition shows that its structure must be square-planar rather than tetrahedral.
