Questions & Step-by-Step Solutions

What is the coordination number of the complex ion [Ni(CN)4]2-?
  • Step 1: Identify the complex ion, which is [Ni(CN)4]2-.
  • Step 2: Look at the central metal ion, which is nickel (Ni).
  • Step 3: Identify the ligands attached to the nickel ion. In this case, there are four cyanide (CN) ligands.
  • Step 4: Count the number of ligands attached to the central metal ion. Here, there are 4 cyanide ligands.
  • Step 5: The coordination number is defined as the number of ligands bonded to the central metal ion.
  • Step 6: Since there are 4 ligands, the coordination number of [Ni(CN)4]2- is 4.
