Incorrect statement of interstitial compounds formed by d-block elements is

Interstitial hydrides are formed when Hydrogen atoms combined with metals. The void present betweeen the metal atoms is filled by hydride ion. Due to which the interstial compound is now inert in nature.The melting points of interstitial compounds are generally higher than those of pure metals because of bonding between the metal and the non-metal hydrogen,  is stronger than metal–metal bonding.
