Step 1: Understand the properties of \( \text{Sn}^{4+} \). Tin in the \( \text{Sn}^{4+} \) state often leads to a smaller ionic radius, which influences its ability to attract and bind ligands in its coordination sphere.
Step 2: Examine typical coordination geometries. For \( \text{Sn}^{4+} \), typical coordination numbers include 6, corresponding to an octahedral geometry. This is supported by its common occurrence in complexes such as \( \text{[SnCl}_6\text{]}^{2-} \).
Step 3: Confirm the maximum coordination number. Given its chemical behavior and common complex formations, \( \text{Sn}^{4+} \) often exhibits a maximum coordination number of 6, allowing it to form stable octahedral complexes.
