The synthesis of inorganic fullerenes is performed at far from equilibrium conditions, and the reaction mechanism involved remains unknown. The discovery of two imperfect structures of nanooctahedra - distorted octahedra and seashell structures is reported and their properties are studied in detail using transmission electron microscopy and quantum-mechanical methods. The imperfect nanoparticles can serve to understand the synthesis route by establishing the basic principles of their morphology and stability.
The fundamental properties of the inorganic lattice are the basis for matching the projections observed in microscopy images with a suggested atomistic model. Quantum-mechanical calculations are used to estimate their stability and electronic properties.
