Advanced Coordination Chemistry Quiz

Coordination Chemistry Overview

• An octahedral complex exhibits a coordination number of 6, meaning it has six ligands bonded to the central metal atom.

Chelating Ligands

• Chelating ligands are molecules that can form multiple bonds to a single metal ion, effectively "grabbing" the metal from multiple points.
• Examples of chelating ligands include EDTA and oxalate.

Common Ligands

• A common ligand in coordination chemistry is water (H2O), which is often referred to as a neutral ligand.
• Other common ligands include ammonia (NH3) and chloride (Cl−).

Bidentate Ligands

• Bidentate ligands are those that can attach to a metal at two separate sites, allowing for stable complex formation.
• An example of a bidentate ligand is ethylenediamine (en).

Geometry of Coordination Complexes

• A complex with a coordination number of 4 typically exhibits a geometry of either tetrahedral or square planar.
• The specific geometry depends on various factors, including the nature of the metal and ligands.

Strong Field Ligands

• Strong field ligands are those that create a significant crystal field splitting, promoting low-spin configurations in metal complexes.
• Examples of strong field ligands include CN− (cyanide) and CO (carbon monoxide).
