Chapter 21, Problem 61RQ

Interpretation Introduction

Interpretation:

The chemical formula of the given coordination complexes is to be determined.

Concept Information:

Complex ions are the ions formed by a metal atom at the center with other non-metal molecules or ions surrounding it.

Ligands are the molecules or ions that are bonded with a coordinate covalent bond to a metal ion.

Coordination complexes are the complexes formed by the coordinate covalent bond between the ligands and the metals.

From the rule of nomenclature of a coordination complex, in the formula of a complex, the symbols for cations or metal ions are written before the anions or ligands.

For writing the formula of the complex having more ligands, like the complex that contains both anionic and neutral ligands, at that condition, the symbols of anionic ligands are written before neutral ligands.

Both the anionic and the neutral ligands are written according to the alphabetical order.
