· JVASP-11165· K2FeNiC6N6

K2FeNiC6N6 is an experimental interstitial metal compound combining potassium, iron, and nickel with carbon and nitrogen ligands, representing research into complex metal nitride-carbide systems. This material belongs to an emerging class of high-entropy or multi-component metal compounds being investigated for potential catalytic, structural, or electrochemical applications where conventional alloys show limitations. While still in the research phase rather than established in mainstream engineering practice, compounds of this type are of interest to materials scientists exploring lightweight alternatives or enhanced reactivity in energy storage, catalysis, and advanced structural applications.
