Question

write the Coordination sphere :​

Answer 1

Answer:

The coordination sphere consists of the central metal ion or atom plus its attached ligands. Brackets in a formula enclose the coordination sphere; species outside the brackets are not part of the coordination sphere. The coordination number of the central metal ion or atom is the number of donor atoms bonded to it.

The central metal ion and ligands linked to it are enclosed in a square bracket. This is called a coordination sphere, which is a discrete structural unit. When the coordination sphere comprising central metal ion and the surrounding ligands together carry a net charge, it is called the complex ion. The ionisable groups shown outside the bracket are the counter ions. For example, the compound$\ K_4[Fe(CN)_6]$ has $\ [Fe(CN)_6]-4$coordination sphere with the ionisable K^⊕ions representing counter ions
