Abstract

Invited for the cover of this issue are the groups of Oliver Oeckler at Leipzig University and Wolfgang Schnick at University of Munich (LMU). The image background depicts a diffraction pattern of an intergrown crystal containing P40 O31 N46 as a night sky. P40 O31 N46 and P74 O59 N84 form complex disordered frameworks, a cutout of which symbolizes the earth's surface (which mainly contains silicates with related building blocks). The structures are built up from chain-like building units, which fall like rain, symbolizing the modular building scheme. Read the full text of the article at 10.1002/chem.202203892.
