Can someone clarify how to determine the shapes of coordination compounds? Like the difference between a tetrahedral complex and a square planar complex?

For coordination compounds, shape is determined by theories such as ligand field theory, which we won't worry about in this class.

The difference between the two just has to do with the shape of the complex. They both have four ligands attached to a central atom, but the difference is that the one configuration forms a square with all of the ligands in the same plane (square planar) and the other configuration has three of the ligands in the same plane and the other in a different plane, forming a tetrahedron shape.
