Donor and Acceptor in Complex Ions of Salts

In complex ions, the donor refers to the atom or group of atoms that donates electron pairs to the central metal ion, while the acceptor refers to the central metal ion that accepts these electron pairs. Let's examine the complex ions in the salts you mentioned and identify the donor and acceptor in each case.

1. K2[SiF6]: - In this salt, the complex ion is [SiF6]2-. The central atom is silicon (Si), and it is surrounded by six fluoride (F) atoms. - The donor in this complex ion is the fluoride ion (F-), which donates its lone pairs of electrons to the silicon atom. - The acceptor in this complex ion is the silicon atom (Si), which accepts the electron pairs from the fluoride ions.

2. [Pt(NH3)2Cl4]: - In this salt, the complex ion is [Pt(NH3)2Cl4]. The central atom is platinum (Pt), and it is surrounded by two ammonia (NH3) molecules and four chloride (Cl-) ions. - The donors in this complex ion are the ammonia molecules (NH3), which donate their lone pairs of electrons to the platinum atom. - The acceptor in this complex ion is the platinum atom (Pt), which accepts the electron pairs from the ammonia molecules.

3. Na3[Cr(CN)6]: - In this salt, the complex ion is [Cr(CN)6]3-. The central atom is chromium (Cr), and it is surrounded by six cyanide (CN-) ions. - The donors in this complex ion are the cyanide ions (CN-), which donate their lone pairs of electrons to the chromium atom. - The acceptor in this complex ion is the chromium atom (Cr), which accepts the electron pairs from the cyanide ions.
