Lithium tricyanomethanide, CAS: 210043-80-4

Key Applications

Advanced Electrolyte & Energy‑Storage Research

• Serves as a high‑stability anionic component for next‑generation lithium battery electrolytes, where the tricyanomethanide anion offers strong charge delocalization and low nucleophilicity.
• Investigated as a lithium‑salt dopant in ionic liquid matrices to improve ionic conductivity and broaden electrochemical windows.
• Useful in solid‑state electrolyte design, particularly in polymer–salt complexes requiring highly dissociated lithium sources.

Organometallic & Coordination Chemistry

• Acts as a versatile ligand precursor, enabling formation of metal–tricyanomethanide complexes with tunable electronic properties.
• Supports synthesis of electron‑poor coordination frameworks, including materials for redox‑active assemblies and molecular electronics.
• Employed in anion‑exchange reactions to introduce the tricyanomethanide motif into metal centers or cationic organic scaffolds.

Organic Synthesis & Functional Materials

• Provides a clean, high‑purity source of the tricyanomethanide anion for nucleophilic substitution, anion metathesis, and construction of highly conjugated, electron‑withdrawing functional groups.
• Used in the preparation of push–pull chromophores, donor–acceptor polymers, and molecular conductors where strong electron‑accepting behavior is required.
• Supports synthesis of ionic organic semiconductors and charge‑transfer materials.

Catalysis & Reaction‑Medium Engineering

• Functions as a weakly coordinating anion in catalytic systems, stabilizing reactive cationic intermediates without interfering with catalytic turnover.
• Useful in ionic‑liquid‑based catalysis, where lithium salts modulate viscosity, polarity, and ion‑pairing behavior.
• Enables development of low‑nucleophilicity reaction media for sensitive transformations.

Materials Science & Specialty Applications

• Applied in the design of electroactive polymers, metal–organic frameworks, and porous materials requiring highly delocalized anions.
• Supports research into high‑dielectric materials and tunable ion‑pair systems for advanced electronics.
• Used in spectroscopic and mechanistic studies where the tricyanomethanide anion provides a distinct, well‑resolved signature.
