    Platonic and Archimedean polyhedra, well-known to mathematicians, have been recently constructed by chemists at a molecular scale by defining the vertices and the edges with metal ions (M) and organic ligands (L), respectively. Here, we report the first synthesis of a concave-surface ' stellated polyhedrong', constructed by extending the faces of its precursor polyhedron until they intersect, forming additional nodes. Our approach involves the formation of an M 12L 24 cuboctahedron core, the linkers of which each bear a pendant ligand site that is subsequently able to bind an additional metal centre to form the stellated M 18L 24 cuboctahedron. During this post-stellation process, the square faces of the M 12L 24 core are closed by coordination of the pendant moieties to the additional metal centres, but they are re-opened on removing these metals ions from the vertices. This behaviour is reminiscent of the analogous metal-triggered gate opening-closing switches found in spherical virus capsids.
