Solution:

Transition elements form compounds of indefinite structures and properties and variable composition which are called Interstitial compounds which are non-stoichiometric compounds formed by the adsorption (penetration) of small, non-metallic atoms like H, B, C, N into the interstices of lattice of transition metals.

Interstitial compound Fe3C (cementite) is formed.
