Chapter 21, Problem 21.71SP

Interpretation Introduction

Interpretation:

The structure of the platinum ethylenediamine ${[Pt{(en)}_2]}^{2+}$ complex is to be draw. The coordination geometry and chelate rings needs to be determined. Also, the coordination number and the oxidation number of the platinum are also to be determined.

Concept introduction:

The coordination number of the element in the coordination complex is calculated by the number of the ligands surrounded by the central metal ion.

The oxidation state of an element is defined as the number assigned to the element which represents the number of elements lost or gained by the atom in the given compound.
