Coordination Compound Flashcard

Chelate
Always require a polydentate ligand in order to be formed
Coordination Number
Number of ligands bound directly to the central metal ion
Ligand
Can be a molecule molecule or anion, monodentate or polydentate
Coordination Compound
Contain a central metal ion with several ligands bounded to it
Coordinate Covalent Bond
Bond formed when one species donates a pair of electrons
Geometric isomer
Also known as disatereomers
Optical Isomer
Have no center, axis, or plane of symmetry
Linkage Isomer
Completes composition remains the same, attachment of ligand donor atom changes
Constitutional Isomer
Formula of completes is the same but the atoms are connected differently
Weak Field Ligand
Create smaller crystal field splitting energies
Strong Field Lignad
Create larger crystal field splitting energies
Low spin complex
Have a lower number of unpaired electrons
High Spin Complex
Have a higher number of unpaired electrons
Crystal Field Splitting Energy
Difference in d orbital energies due to presence of ligand in a given geometry
Spectrochemical series
Ranks ligands in their ability to split d orbital energies
Transition Metal
Formed when d orbitals begin to fill
Cis-Isomer
Identical ligands on same side of metal atom
Trans-Isomer
Identical ligands on opposite side of metal atom
