Tetrahedral complexes of Co2+ are quite common. Use a d-orbital splitting diagram to rationalize the stability of Co2+ tetrahedral complex ions.

Interpretation Introduction

Interpretation: The rationalization of the stability of Co2+ tetrahedral complex is to be stated.

Concept introduction: The complex ions or compounds are said to be stable if the energy levels of these compounds or ions are completely filled or half filled.

To rationalize: The stability of Co2+ tetrahedral complex.

Explanation of Solution

Explanation

The atomic number of central atom cobalt (Co) is 27 and its electronic configuration is,

1s22s22p63s23p63d74s2

The electronic configuration of cobalt (Co2+) for the oxidation state +2   is,

1s22s2
