Chapter 21, Problem 35E

(a)

Interpretation Introduction

Interpretation: The name of the given structures of complex ion is to be stated.

Concept introduction: Rules followed in the naming of coordination compound:

• In naming of coordination compound, the name of anion (ligand) comes first. Metal ion is named second, which is the name of element.
• An ‘o’ is added to the root name of anion.
• Greek prefix is used to express the number of ligands.
• Roman numeral is used to denote the oxidation state of metal ion.
• In case of more than one type of ligand present in a compound, they are named alphabetically.
• The suffix ‘-ate’ is added to metal ion if complex ion contains negative charge. Latin names are also used to identify the name of metals.

To determine: The name of the given structure of complex ion.
