Examples of a complete series of coordination isomers require at least two metal ions and sometimes more. For example, a solution containing ([Co(NH 3) 6] 3+ and [Cr(CN) 6] 3−) is a coordination isomer with a solution containing [Cr(NH 3) 6] 3+ and [Co(CN) 6] 3−.
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 ...
In coordination chemistry, ligand isomerism is a type of structural isomerism in coordination complexes which arises from the presence of ligands which can adopt different isomeric forms. 1,2-Diaminopropane and 1,3-Diaminopropane are the examples that each feature a different isomer would be ligand isomers.
For metal ions that prefer octahedral coordination, these complexes often adopt the stoichiometry M(aa) 3 (aa = amino carboxylate, such as glycinate, H 2 NCH 2 CO 2 −). Complexes of the 3:1 stoichiometry have the formula is [M(O 2 CC(R)HNH 2) 3] z. Such complexes adopt octahedral coordination geometry. These complexes can exist in facial and ...
Sulfoxides can bind to metals by the oxygen atom or by sulfur. This dichotomy is called linkage isomerism. O-bonded sulfoxide ligands are far more common, especially for 1st row metals. S-bonded sulfoxides are only found for soft metal centers, such as Ru(II). Complexes with both O- and S-bonded sulfoxide ligands are known. [4]
In coordination chemistry, a bridging ligand is a ligand that connects two or more atoms, usually metal ions. [1] The ligand may be atomic or polyatomic. Virtually all complex organic compounds can serve as bridging ligands, so the term is usually restricted to small ligands such as pseudohalides or to ligands that are specifically designed to ...
A triazole is a heterocyclic compound featuring a five-membered ring of two carbon atoms and three nitrogen atoms with molecular formula C 2 H 3 N 3.Triazoles exhibit substantial isomerism, depending on the positioning of the nitrogen atoms within the ring.
Coordination Chemistry is the science concerned with the interactions of organic and inorganic ligands with metal centres. It studies the physical and chemical properties, syntheses and structures of coordination compounds .
