The Gregory–Newton problem of kissing hard spheres transferred to chemistry can be formulated as: what is the highest possible coordination number for an atom? First‐principles quantum chemical simulations of the Pb 2+ –He interactions revealed a remarkably stable PbHe 15 2+ with all He atoms in the first coordination sphere. The picture shows the HOMO of this ion.
