Largest hollow cage molecule yet made from 1000 atoms

Giant polyoxymetalate cluster contains 240 molybdenum, 740 oxygen and 20 sulfur atoms

A giant hollow molecule containing 1000 atoms self-assembled into an unusual pentagonal dodecahedron has been created by researchers in China. The molecule’s 240 molybdenum ions make it the highest nuclearity hollow dodecahedra cage ever reported – and it’s a superb proton conductor, too.
