Summary

Coordination compounds are important in biology, industry, and everyday materials. This lesson introduces how a central metal and its ligands form a coordination complex.

In many main-group compounds, atoms share or transfer valence electrons to form bonds. Transition-metal complexes commonly form coordinate covalent bonds instead. In this type of bond, both bonding electrons are supplied by one partner.

All flashcards

Coordinate covalent bond
A covalent bond in which one partner supplies both electrons in the shared pair.
Denticity
The number of donor atoms from one ligand that bind to a metal.
Chelating ligand
A ligand that binds a metal through multiple donor atoms.
Enantiomers
Nonsuperimposable mirror-image forms of the same compound.
Ionization isomerism
Isomerism caused by exchanging an inner-sphere ligand with an outer-sphere counterion.

Quiz questions

  1. What is the oxidation state of platinum in [PtCl6]2−[PtCl_6]^{2-}?Answer: +4
  2. How is the metal name modified when naming an anionic coordination complex?Answer: It commonly takes an -ate ending.
  3. Which geometries are both possible for a four-coordinate complex?Answer: Tetrahedral and square planar
  4. What causes linkage isomerism in a coordination complex?Answer: A ligand binds through different possible donor atoms.
  5. How does a catalyst affect a chemical reaction?Answer: It lowers activation energy and is regenerated overall.
