Answer: only one kind of donor ligand.
- A only anionic ligands
- B two different kinds of ligands
- C only one kind of donor ligand
- D only neutral ligands
Correct answer: C. only one kind of donor ligand
Explanation: A homoleptic complex has a metal coordinated to only one type of ligand, e.g. [Co(NH<sub>3</sub>)<sub>6</sub>]<sup>3+</sup>. Heteroleptic complexes have more than one kind of ligand.
The three common coordination geometries: octahedral (6 ligands), tetrahedral (4 ligands), and square planar (4 ligands in one plane).
Concept context
Study of compounds where a central metal atom is bonded to surrounding ligands. Covers nomenclature, types of isomerism, bonding theories (VBT, CFT), and applications in medicine, photography, and industry.
