Secondary Valence
In Werner's theory, the non-ionisable valence corresponding to the coordination number, satisfied by ligands in fixed spatial positions.
Inorganic & Coordination ChemistrySlag
The molten by-product formed when a flux combines with the gangue during smelting.
Inorganic & Coordination ChemistrySpectrochemical Series
A ranking of ligands by the magnitude of the crystal field splitting they produce.
Inorganic & Coordination ChemistrySquare Planar Complex
A four-coordinate complex in which the ligands occupy the corners of a square around the metal.
Inorganic & Coordination ChemistryStability of Complexes
The thermodynamic tendency of a complex to persist rather than dissociate into metal ion and free ligands.
Inorganic & Coordination ChemistryStrong Field Ligand
A ligand that produces a large crystal field splitting, favouring electron pairing over occupation of upper orbitals.
Inorganic & Coordination ChemistryTetrahedral Splitting
The division of d orbitals under a tetrahedral field, with the e set below the t₂ set and a much smaller gap.
Inorganic & Coordination ChemistryValence Bond Theory of Complexes
The model describing coordinate bonding as the overlap of filled ligand orbitals with hybridised empty orbitals on the metal.
Inorganic & Coordination ChemistryVan Arkel Process
A purification method in which a metal is converted to a volatile iodide and then decomposed on a hot filament.
Inorganic & Coordination ChemistryWeak Field Ligand
A ligand that produces only a small crystal field splitting, so electrons occupy upper orbitals rather than pairing.
Inorganic & Coordination ChemistryWerner's Theory
The 1893 theory proposing that metals exhibit two types of valence and that ligands occupy fixed positions in space around the metal.
Inorganic & Coordination ChemistryZone Refining
An ultra-purification technique in which a narrow molten zone is passed repeatedly along a solid rod.
