Questions & Step-by-Step Solutions

What is the coordination number of the central metal ion in a complex with the formula [Co(NH3)6]Cl3?
  • Step 1: Identify the central metal ion in the complex. In this case, the central metal ion is Co (Cobalt).
  • Step 2: Look at the ligands attached to the central metal ion. In this formula, there are six NH3 ligands.
  • Step 3: Count the number of ligands. Here, we have 6 NH3 ligands.
  • Step 4: The coordination number is equal to the number of ligands attached to the central metal ion.
  • Step 5: Since there are 6 NH3 ligands, the coordination number of the central metal ion Co is 6.
