  • 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.
