Matryoshka doll icosahedral cluster

The isolable matryoshka nesting doll icosahedral cluster [As@Ni₁₂@As₂₀]^3– as a superatom: analogy with the jellium cluster Al₁₃^– generated in the gas phase by laser vaporization
R. Bruce King and Jijun Zhao

The valence electrons in the recently reported icosahedral cluster [As@Ni₁₂@As₂₀]^3– with a Russian matryoshka nesting doll structure can be partitioned so that the central As atom has the rare gas configuration, as As^3–, and the intermediate Ni₁₂ icosahedron receives 40 electrons from the lone pairs of the outer As₂₀ dodecahedron to be isoelectronic with the Al₁₃^– jellium cluster found in molecular beam experiments.
