Coordination compound meaning
WebCoordination compounds definition. A coordination compound is a compound containing a coordination complex. A coordination complex is a molecule where the center is a metal atom bonded to several other. atoms/molecules called ligands. A complex ion is a coordination complex with a charge. WebCoordination compounds have been known and used since antiquity; probably the oldest is the deep blue pigment called Prussian blue: KFe 2(CN) 6. The chemical nature of these substances, however, was unclear for a number of reasons. For example, many compounds called “double salts” were known, such as AlF 3 · 3KF, Fe(CN) 2 · 4KCN, …

WebAug 15, 2024 · Jim Clark. Truro School in Cornwall. A complex ion has a metal ion at its center with a number of other molecules or ions surrounding it. These can be considered to be attached to the central ion by coordinate (dative covalent) bonds (although in some cases, the bonding is actually more complicated than that.) 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 or complexing agents. Many metal-containing compounds, especially those that include transition metals (elements like titanium that belong to the Periodic Table's d-block), are coordination complexes.
