The shape of germanium clusters to come.
A different drummer: The existence of endohedral germanium clusters was predicted earlier by gas-phase experiments. The [Co@Ge(10)](3-) anion now synthesized is surprising, as it breaks with a long line of exclusively deltahedral structures found in the past. Instead, it has a regular pentagonal-prismatic structure (see picture; Co gray, Ge red).
