Square planar
From Wikipedia, the free encyclopedia
The square planar molecular geometry in chemistry describes the spatial arrangements of atoms in a chemical compound
In this geometry co-ordination can be imagined to result when two ligands on the z-axis of an octahedron are removed from the complex, leaving only the ligands in the x-y plane. As the z-ligands move away, the ligands in the square plane move a little closer to the metal. So the orbital splitting diagram for square planar coordination can thus be derived from the octahedral diagram. dz2 falls most in energy. dxz and dyz also drop in energy but not as much. Conversely, dx2-y2 and dxy increase in energy.
Examples of organometallic compounds with this geometry are Vaska's complex and Crabtree's catalyst
