Square Planar Complexes Coordination compounds with a unique d-orbital splitting pattern due to ligand interactions on the x and y axes. d-Orbitals Atomic orbitals involved in bonding, exhibiting different energy levels in square planar complexes. Ligands Molecules or ions that interact with metal centers, affecting d-orbital energy levels. X Axis One of the axes along which ligands interact strongly with d-orbitals in square planar complexes. Y Axis The other axis along which ligands interact strongly with d-orbitals in square planar complexes. d(x2-y2) The highest energy d-orbital in square planar complexes, interacting strongly with x and y axes. dxy A d-orbital with significant interaction with both x and y axes, having the second highest energy. dz2 A d-orbital with moderate interaction with x and y axes, forming a disc shape. dyz A d-orbital interacting primarily with the y axis, having lower energy in square planar complexes. dxz A d-orbital interacting primarily with the x axis, having lower energy in square planar complexes. Crystal Field Splitting The energy difference between d-orbitals due to ligand interactions in coordination complexes. Splitting Energy (Δ) The energy difference between the highest and lowest d-orbitals in a complex. Degenerate Orbitals Orbitals with the same energy level, such as dyz and dxz in square planar complexes. Energy Gradient The variation in energy levels of d-orbitals due to differing ligand interactions. Coordination Geometry The spatial arrangement of ligands around a central atom in a complex.
