Discuss preparation and properties of KMnO_4

KMnO_(4) is prepared by

Introduction of d-block elements: - position in periodic table| Trick to learn d-block elements and d-block elements vs transition elements

d-block elements form complex compounds, Give reason.

Due to availability of vacant orbitals of sufficiently low energy, d-block elements form complexes, d-block elements have different properties such as-catalytic, magnetic, alloy formation, interistitial compounds formation. Interistitial compounds are those compound in which small atoms like carbon and boron fits into interistices of d-block elements crystal. in interistitial compounds, there is no chemical bond formation. chemcial properties remain almost same but physical properties may change. Q. Which of the property of interistitial compounds has the same behaviour as that of the elements?
