Textbook: Open Stax Chemistry 2e

Suggested Reading: Chapter 19.1-19.2

Learning Objectives:

• List the defining traits of coordination compounds
• Calculate d-electron count of a metal given its oxidation number or charge
• Calculate the oxidation number of a central atom within a coordination compound
• Recognize ligands within coordination compounds as common, previously studied structures

• Complex ions are formed by ligand-metal bonds that are similar to covalent bonds, but differ in that both electrons come from the ligand. Figure 19.13 (a) Covalent bonds involve the sharing of electrons by Open Stax is licensed under CCBY 4.0.
• Complex ions can form geometries that can appear more sophisticated than previous geometries, but all will behave like a single ion when forming a compound. Figure 19.14 The complexes (a) [Ag(NH3)2]+ by Open Stax is licensed under CCBY 4.0.
