A 2x2 grid of diagrams. One column is labelled "high humidity" and the other is labelled "low humidity" The top row contains ball-and-stick chemical models, while the bottom row contains a more simplified, structural view. In both cases, the high humidity column has a hexagonal ordering, whereas the low humidity column shows a layered structure.
