In chemistry, linkage isomerism or ambidentate isomerism is a form of structural isomerism in which certain coordination compounds have the same composition but differ in which atom of the ligand is bonded to the metal. Typical ligands that give rise to linkage isomers are: cyanide, CN − – isocyanide, NC −; cyanate, OCN − – isocyanate ...
In one isomer the CO ligands are terminal. When a pair of CO are bridging, cis and trans isomers are possible depending on the location of the C 5 H 5 groups. [7] Another example in organometallic chemistry is the linkage isomerization of decaphenylferrocene, [(η 5-C 5 Ph 5) 2 Fe]. [8] [9] Formation of decaphenylferrocene from its linkage isomer
In coordination chemistry, a ligand [a] is an ion or molecule with a functional group that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electron pairs, often through Lewis bases. [1]
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.
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]
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 chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers. Isomers do not necessarily share similar chemical or physical properties.
