The freezing point depression produced by a one-molal solution of a non-electrolyte in a given solvent.
K_f = RT_f²M / ΔH_fus
Crystal Defect
States of Matter & Gas Laws
Dimensionless
Any irregularity that interrupts the perfectly ordered arrangement of particles in a crystal.
Crystal Field Splitting Energy
Inorganic & Coordination Chemistry
cm⁻¹
The energy difference between the sets of d orbitals produced when a ligand field lifts their degeneracy.
Δ₀ or Δ_t
Crystal Field Stabilisation Energy
Inorganic & Coordination Chemistry
kJ/mol
The net energy gained by a complex through the preferential occupation of lower-energy d orbitals.
CFSE = (−0.4n_t2g + 0.6n_eg)Δ₀
Crystal Field Theory
Inorganic & Coordination Chemistry
kJ/mol
The model treating metal–ligand bonding as purely electrostatic and analysing how ligand fields split the metal d orbitals.
Crystal Lattice
Chemical Bonding & Molecular Structure
Dimensionless
The regular, repeating three-dimensional arrangement of particles in a crystalline solid.
Crystalline Solid
States of Matter & Gas Laws
Dimensionless
A solid in which the constituent particles are arranged in a regular, repeating three-dimensional pattern extending over long distances.
Crystallisation
Foundations of Chemistry
Dimensionless
A purification technique in which a solid is separated from solution as an ordered crystalline lattice.
