Phase diagram of CeIn2Ni9 with Orb v3 conservative inf MPA; e_above_hull: 0.165301 eV/atom; predicted_stable: False
CeIn₂Ni₉ CaCu₅-derivative structure (P6/mmm, No. 191, 12 atoms) built from hexagonal CaCu₅ derivative. Source: Nop, Mundy, Smith & Paudyal, npj Comput. Mater. (2025).
Testing five topological misclassified compounds from Nop et al. (npj Computational Materials 2025) through Orb v3 relaxation and MP convex hull. 3/5 collapsed or degraded, revealing overlap between topology misclassification and structural failure.
