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 As3–, 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.
