Answer 2

If the anion is complex and cation is simple in nature it is called coordination centre

Explanation:

1. chemical compound in which the central ion or atom (or the coordination centre) is bound to a set number of atoms, molecules, or ions is called a coordination entity. Some examples of such coordination entities include [CoCl3(NH3)3], and [Fe(CN)6]4-.

2.A metal complex or coordination compound is formed by the association of a metal atom or ion and another chemical species, called ligand, which may be either an anion or a polar molecule.

3.Werner's theory states that- 1. Metals possess two types of valencies called primary / ionizable and secondary / non - ionizable valency. 2. Every metal atom has a tendency to satisfy both its primary and secondary valencies.
