d block elements mostly form

The colour of d-block elements is due to:

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?
