Cm2V

Cm2V is an intermetallic compound described in some discussions of actinide–transition metal systems as having two curium atoms for every one vanadium atom (stoichiometry Cm2V). Detailed, peer‑reviewed information on a distinct Cm2V phase is scarce, and many references treat the Cm–V system more generally rather than documenting a verified Cm2V crystal structure.

Synthesis and handling of Cm2V, if it can be prepared, would require specialized facilities due to the radioactivity of curium. Curium is produced in nuclear reactors or particle accelerators and compounds containing Cm are typically formed under inert or reducing conditions to avoid oxide formation. Any intermetallic involving Cm and a reactive metal like vanadium would likely be produced by high-temperature alloying or direct reaction in sealed, corrosion-resistant crucibles, with rigorous radiological controls.

Structure and properties for Cm2V are not definitively established in the standard literature. If a Cm2V phase exists, its structure would depend on processing and phase relations in the Cm–V system and could be a metallic intermetallic with a high melting point. Characteristics common to Cm-containing intermetallics include high density, metallic conductivity, and strong radiological hazards. As with other actinide compounds, chemical reactivity in air can be an issue, and oxides form readily upon exposure.

Occasionally, Cm2V is cited in databases or theoretical discussions as part of broader surveys of actinide–transition metal chemistry. It remains primarily of academic interest for understanding bonding and phase behavior in actinide alloys rather than any practical application.
