The cuboctahedron consists of copper paddle-wheel nodes and carborane–isophthalic acids
Scientists in the US have made a molecular species containing the highest number of boron atoms ever recorded in a crystallographically characterised molecular species. The unique supramolecular cuboctahedron contains 240 boron atoms and was synthesised by Chad Mirkin and colleagues at Northwestern University in Evanston, Illinois, via coordination-driven assembly.
