Chapter 23.3, Problem 23.3AFP

(a)

Interpretation Introduction

Interpretation:

The coordination number and the charge of the central metal ion in $\left[Co{(en)}_{2}B{r}_2\right]N{O}_3$ coordination Compound has to be given.

Concept introduction:

The charge of the complex ion can be determined from the charge of its counter ion(s) and basic arithmetic can be used to find the charge of the metal ion:

  $\text{Charge}\text{of}\text{ion}\text{=}\text{charge}\text{of}\text{ion}\text{-}\text{total}\text{charge}\text{of}\text{ligands}$

The coordination number is the number of ligand atoms bonded directly to the central metal ion in a complex ion.

(b)

Interpretation Introduction

Interpretation:

The coordination number and the charge of the central metal ion in $M{g}_3{\left[CrC{l}_{5}Br\right]}_2$ coordination Compound has to be given.

Concept introduction:

The charge of the complex ion can be determined from the charge of its counter ion(s) and basic arithmetic can be used to find the charge of the metal ion:

  $\text{Charge}\text{of}\text{ion}\text{=}\text{charge}\text{of}\text{ion}\text{-}\text{total}\text{charge}\text{of}\text{ligands}$

The coordination number is the number of ligand atoms bonded directly to the central metal ion in a complex ion.
