Coordination sphere : ウィキペディア英語版 | Coordination sphere
In coordination chemistry, the coordination sphere refers to a central atom or ion and an array of molecules or anions, the ligands, around. 〔(chemistry-dictionary.com - Definition of coordination sphere )〕 〔(''What Is A Coordination Compound?'' )〕 Molecules that are attached noncovalently to the ligands are called the second coordination sphere. ==First coordination sphere== The first coordination sphere refers to the molecules that are attached directly to the metal. These molecules are typically solvent. The interactions between the first and second coordination spheres usually involve hydrogen-bonding. For charged complexes, ion-pairing is important. In hexamminecobalt(III) chloride (()Cl3), the cobalt cation plus the six ammonia ligands comprise the first coordination sphere. The coordination sphere of this ion thus consists of a central MN6 core "decorated" by 18 N-H bonds that radiate outwards.
