A coordination compound (or coordination complex) consists of a metal cation or neutral atom to which neutral or negatively charged ligands have bonded. Key Terms. The organic chemist often deals with diamagnetic compounds which are Coordination compounds are a class of compounds that we know as the complex compounds. 2. A major application of coordination compounds is their use as catalysts, which serve to alter the rate of chemical reactions. We have known enough about these compounds already, including their structuresand isomers etc. • If the complex bears a charge, it is a complex ion. Coordination compounds have applications in day-to-day life. Overview of Applications Of Coordination Compounds. Transcript Coordination Chemistry PPT Chemistry of Coordination Compounds Chemistry of Coordination Compounds Complexes • A central metal atom bonded to a group of molecules or ions is a metal complex. Due to tetrahedral coordination by weak-field sulfur ligands, the iron is high spin in both the Fe 3 + and Fe 2 + oxidation states, which results in similar structures for the oxidized and reduced forms of the Fe–S complexes. Wilkinson’s catalyst has a square planar coordination geometry; It reacts with carbon monoxide to yield [RhCl(CO)(PPh 3) 2] This coordination compound undergoes dimerization when stirred into a solution of benzene.
