Six isomers of bipyridine exist, but two are prominent. 2,2′-bipyridine , also known as bipyridyl, dipyridyl, and dipyridine, is a popular ligand in coordination chemistry [ 2 ] [ 3 ] 2,2′-Bipyridine
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, 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.
In traditional names various qualifiers are used to label isomers, for example, isopropanol (IUPAC name: propan-2-ol) is an isomer of n-propanol (propan-1-ol). The term moiety has some overlap with the term "functional group". However, a moiety is an entire "half" of a molecule, which can be not only a single functional group, but also a larger ...
Molecular binding occurs in biological complexes (e.g., between pairs or sets of proteins, or between a protein and a small molecule ligand it binds) and also in abiologic chemical systems, e.g. as in cases of coordination polymers and coordination networks such as metal-organic frameworks.
A tridentate ligand (or terdentate ligand) is a ligand that has three atoms that can function as donor atoms in a coordination complex. [1] Well-known tridentate ligands include diethylenetriamine with three nitrogen donor atoms, and the iminodiacetate anion which consists of one deprotonated amine nitrogen and a pair of carboxylate groups.
