The cover picture shows a hydrogen‐bonded framework complex which exhibits an interesting phase transitionbehavior. After removing coordinated water of the complex (top left), an amorphous powder (bottom right) was obtained. The amorphous powder can be restored to the complex by reintroducing water. The fact suggests that the complex exhibits a reversible crystal‐to‐amorphous transformation property triggered by coordinated water removing/reintroduction and unaccompanied by lattice solvents releasing/loading. This is contrary to the generally accepted idea that complexes transform their structures reversibly accompanied by lattice solvents releasing/loading. More details are discussed in the article by W. Xiao et al. on p. 1511ff.
