Question

What are interstitial compounds? why are such compounds well known for transition metals?

Answer 1

An interstitial compound formed when a atom with a small enough radius sits in an interstitial hole in the metal lattice

Answer 2

Hey !!

Interstitial compounds are those in which small atoms occupy the interstitial sites in the crystal lattice. Interstitial compounds are well known for transition metals because small-sized atoms of H , B , C , N, etc can easily occupy position in the voids present in the crystal lattices of transition metals.

Hope it helps you !!
