Introduction
•
Complex compounds are those in which the metal ions
bind a number of anions or neutral molecules giving complex species with
characteristic properties.
•
A few examples are: [Fe(CN)6]3–,
[Fe(CN)6]4–, [Cu(NH3)4]2+ and
[PtCl4]2–.
•
The transition metals form a large number of complex
compounds.
This is due to the
comparatively smaller sizes of the metal ions, their high ionic charges and the
availability of d orbitals for bond formation.
