What is the geometry of the complex ion [Ni(CN)4]2-?
Correct Answer: Square planar
- Step 1: Identify the central metal ion in the complex. In this case, it is nickel (Ni).
- Step 2: Count the number of ligands attached to the nickel ion. Here, there are 4 cyanide (CN) ligands.
- Step 3: Determine the coordination number of the nickel ion. Since there are 4 ligands, the coordination number is 4.
- Step 4: Understand the geometry associated with a coordination number of 4. This typically leads to either tetrahedral or square planar geometry.
- Step 5: Consider the nature of the ligands. Cyanide (CN) is a strong field ligand, which favors square planar geometry.
- Step 6: Conclude that the geometry of the complex ion [Ni(CN)4]2- is square planar.
