Overview

Coordination compounds are molecular or addition compounds in which a central metal atom or ion is permanently attached to ligands by coordinate bonds. These compounds keep their identity in solution and show properties different from those of their constituent ions. The chapter explains their basic

Key Concepts

These are compounds in which

These are compounds in which a central metal atom or ion is directly attached to ligands. Ligands donate electron pairs to the metal through coordinat

Double salts exist in the solid

Double salts exist in the solid state but dissociate completely into their constituent ions when dissolved in water. They lose their identity in solut

Ligands are atoms

Ligands are atoms, ions, or molecules that donate lone pair electrons to the central metal atom or ion. They may be neutral, anionic, or rarely cation

A polydentate ligand that attaches through

A polydentate ligand that attaches through two or more donor atoms and forms a five- or six-membered ring with the metal ion is a chelating ligand. Th

Werner proposed that metals show primary

Werner proposed that metals show primary valency and secondary valency. Primary valency is ionisable and corresponds to oxidation state. Secondary val

Learning Objectives

  • Define coordination compounds, ligands, coordination sphere, ionic sphere, and coordination number
  • Distinguish coordination compounds from double salts
  • Classify ligands by charge and denticity
  • Explain chelation and the extra stability of chelates
  • Understand Werner's theory and primary and secondary valencies
