Chapter 24, Problem 2E

Interpretation Introduction

(a)

Interpretation:

The coordination number of the central metal ion and its oxidation state in the given complex ${[Co{(N{H}_3)}_6]}^{2+}$ should be determined. Name of the complex should also be given.

Concept introduction:

The coordination number of any complex is established by the total number of ions or atoms proximately surrounding or nearest to the central atom in a crystal or compound.

The oxidation number of an atom is equivalent to the charge on the ion, e.g. Na+ has the oxidation number of +1 and O²- has -2. In a molecule or compound, it is the sum of the oxidation numbers of its component atoms. The total charge of the ligands is deducted from the overall charge of the coordinate complex.

When any complex is named, the ligands are named foremost, in the alphabetical order, and the metal atom or ion is named afterward. Conversely, in the chemical formula, the metal atom or ion is marked before the ligands.
