Coordination Compound
coordination compound[kō‚ȯrd·ən′ā·shən ‚käm‚pau̇nd] (chemistry) A compound with a central atom or ion and a group of ions or molecules surrounding it. Also known as coordinated complex; Werner complex. Coordination Compound any of a group of compounds of complex composition. In these compounds, molecules of water, ammonium, acids, and salts are added to the complex ion. Examples of coordination compounds are crystal hydrates of the [Co(NH3)6]2(SO4)3·5H2O, type, various ammoniates, such as Cu[PtCl6]·18NH3, and various salts, such as (NH4)3[RuCl6]NH4NO3. Possessing an electrostatic field, the complex ion attracts dipolar molecules, forming in solution a second or even a third coordination sphere. The formation of coordination compounds can involve oxidation-reduction reactions, Van der Waals forces, and hydrogen bonds. Coordinated molecules or ions, for example, SCN– in the compound [(NH3)2PtSCNSCNAg]NO3, can serve as secondary centers of addition. REFERENCESGrinberg, A. A.
