Compared to the first coordination sphere, the second coordination sphere has a less direct influence on the reactivity and chemical properties of the metal complex. Nonetheless the second coordination sphere is relevant to understanding reactions of the metal complex, including the mechanisms of ligand exchange and catalysis.
This intermediate is then heated to induce coordination of one of the outer sphere chloride ligands: [Co(NH 3) 5 (OH 2)]Cl 3 → [Co(NH 3) 5 Cl]Cl 2 + H 2 O. The dication [Co(NH 3) 5 Cl] 2+ has idealized C 4v symmetry. [3] [4] In an aqueous solution, chloropentaamminecobalt(III) chloride reforms aquopentammine complex.
Chloro(pyridine)cobaloxime is a coordination compound containing a Co III center with octahedral coordination. It has been considered as a model compound of vitamin B 12 for studying the properties and mechanism of action of the vitamin.
Cisplatin, PtCl 2 (NH 3) 2, is a coordination complex of platinum(II) with two chloride and two ammonia ligands.It is one of the most successful anticancer drugs. A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands ...
Hexaamminecobalt(III) chloride is the chemical compound with the formula [Co(NH 3) 6]Cl 3.It is the chloride salt of the coordination complex [Co(NH 3) 6] 3+, which is considered an archetypal "Werner complex", named after the pioneer of coordination chemistry, Alfred Werner.
In coordination chemistry, the ligand cone angle (θ) is a measure of the steric bulk of a ligand in a transition metal coordination complex. It is defined as the solid angle formed with the metal at the vertex of a cone and the outermost edge of the van der Waals spheres of the ligand atoms at the perimeter of the base of the cone.
In chemistry, metal aquo complexes are coordination compounds containing metal ions with only water as a ligand. These complexes are the predominant species in aqueous solutions of many metal salts, such as metal nitrates, sulfates, and perchlorates. They have the general stoichiometry [M(H 2 O) n] z+.
The coordination geometry of an atom is the geometrical pattern defined by the atoms around the central atom. The term is commonly applied in the field of inorganic chemistry, where diverse structures are observed. The coordination geometry depends on the number, not the type, of ligands bonded to the metal centre as well as their locations.
