Write the formula for a complex formed between zn2 zn2 and nh3nh3 with a coordination number of 3.
fredd [130]

Triammine zinc sulfate is the formula for a compound produced between zn2 and nh3 with a coordination number of 3.

<h3>Steps</h3>

Zinc atoms are present in the +2 oxidation state in zinc sulfate (ZnSO4).

Thus, a coordination complex formed by three ammonia ligands and zinc sulfate can be shown below.

NH3 + ZnSO4 = [Zn(NH3)] SO4

In its ionic form, this equation can be expressed as

Zn²⁺ + 3NH₃ = [Zn(NH₃)₃]²⁺

<h3>Coordination number: what is it?</h3>

The number of atoms, ions, or molecules that a central atom or ion in a complex, coordination compound, or crystal holds as its closest neighbors.

<h3>What is a good illustration of a coordination number?</h3>

For instance, [Cr(NH3)2Cl2Br2] has the core cation Cr3+, which is referred to as hexacoordinate and has a coordination number of 6.
