For the complex ion $[Mn(NH3)2(H2O)3(OH) ]2+$ ,

Co-ordination number of the metal atom has to be known.

Concept Introduction:

Complex compounds are primarily formed by transition elements which are d-block elements. A co-ordination compound is known as a complex compound is made of metal atom/ion and ligand(s). Ligands are considered as Lewis bases and the central metal atom is Lewis acid. Ligands donate a pair of electron to metal ion and establish bonding with metal ion which is known as co-ordinate bond and hence these compounds are named as co-ordination compounds. The ligands represented inside the square brackets adjacent to the central metal ion, which is termed as co-ordination sphere.

Co-ordination number of a complex compound refers to the number of ligands bonded to central metal atom.

Oxidation number or oxidation state of an element refers to the charge it carries in its elemental state and in its compounds.

Some of the rules for assigning oxidation number to an element are stated below -

Oxidation number of an element in its pure elemental form is zero.

Oxidation number of a mono atomic ion is equivalent to charge of the mono atomic ion.

Oxidation state of Fluorine is always $−1.$

Sum of oxidation numbers of all atoms in a neutral compound becomes zero.

Interpretation Introduction

Interpretation:

For the complex ion $[Mn(NH3)2(H2O)3(OH) ]2+$ ,

Charge on the complex has to be determined by assuming all the ligands are $Cl$ ligands.
