The given compounds are to be named. Concept Information: Complex ions are the ions formed by the metal atom at the center and 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. Coordinate complexes are the those that are formed by the coordinate-covalent bond between ligands and metals. Rules of nomenclature for coordination complexes: Cationic species are named before anionic species. The names of anionic ligands always end in the suffix -o . A neutral ligand is given the same name as the neutral molecule. When there is more than one, of a particular ligand, their number is specified by the prefixes di- = 2, tri- = 3, tetra- = 4, penta- = 5, hexa- = 6 , and so forth. When confusion might result by using these prefixes, the following are used instead: Bis- = 2, tris= 3, and tertakis- = 4 . In the name of the complex, the ligands are named first, in alphabetical order without regard to charge, followed by the name of the metal. Negative (anionic) complex ions always end in the suffix -ate. The oxidation state of the metal in the complex is written in Roman numerals within parentheses following the name of the metal.

Interpretation Introduction

Interpretation:

The given compounds are to be named.

Concept Information:

Complex ions are the ions formed by the metal atom at the center and 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.

Coordinate complexes are the those that are formed by the coordinate-covalent bond between ligands and metals.

Rules of nomenclature for coordination complexes:

Cationic species are named before anionic species.

The names of anionic ligands always end in the suffix -o.

A neutral ligand is given the same name as the neutral molecule.

When there is more than one, of a particular ligand, their number is specified by the prefixes di- = 2, tri- = 3, tetra- = 4, penta- = 5, hexa- = 6, and so forth. When confusion might result by using these prefixes, the following are used instead: Bis- = 2, tris= 3, and tertakis- = 4.

In the name of the complex, the ligands are named first, in alphabetical order without regard to charge, followed by the name of the metal.

Negative (anionic) complex ions always end in the suffix -ate.

The oxidation state of the metal in the complex is written in Roman numerals within parentheses following the name of the metal.
