Problem

The coordination number for Mg2+ ion is usually six. Assuming this assumption holds, determine the anion coordination number in the following compounds.

MgS

Solution

We are asked to identify the coordination number of the anion in MgS.

We are given that the coordination number for Mg2+ ion is usually six and this assumption holds. To answer this, we shall use the following equation:

Anion C.N. = Cation C.N.(# of cations per formula unit# of anions per formula unit)

Where: C.N. = Coordination Number
