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 ...
The combination of a coordination cage and a guest is a type of inclusion compound. Coordination complexes can be used as "nano-laboratories" for synthesis, and to isolate interesting intermediates.

The usual synthesis involves treatment of a metal salt with acetylacetone, acacH: [2] [page needed] M z+ + z Hacac ⇌ M(acac) z + z H + Addition of base assists the removal of a proton from acetylacetone and shifts the equilibrium in favour of the complex. Both oxygen centres bind to the metal to form a six-membered chelate ring.
The mixture is a colorless liquid. These tautomers interconvert so rapidly under most conditions that they are treated as a single compound in most applications. [2] Acetylacetone is a building block for the synthesis of many coordination complexes as well as heterocyclic compounds.
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.
A coordination polymer is an inorganic or organometallic polymer structure containing metal cation centers linked by ligands. More formally a coordination polymer is a coordination compound with repeating coordination entities extending in 1, 2, or 3 dimensions. [1] [2] It can also be described as a polymer whose repeat units are coordination ...
Chloropentamminecobalt chloride is the dichloride salt of the coordination complex [Co(NH 3) 5 Cl] 2+. It is a red-violet, diamagnetic, water-soluble salt. The compound has been of academic and historical interest.
18-Crown-6 can be synthesized by the Williamson ether synthesis using potassium ion as the template cation. Structure of nickel-aquo nitrate complex of the ligand derived from the templated trimerization of 2-aminobenzaldehyde. [5] The phosphorus analogue of an aza crown can be prepared by a template reaction. [6]
