What are interstitial compounds? Why are such compounds well known for transition
Transition metals are large in size and contain lots of interstitial sites. Transition elements can trap atoms of other elements (that have small atomic size), such as $H , C , N ,$ in the interstitial sites of their crystal lattices. The resulting compounds are called interstitial compounds.
