The cover picture shows a chiral (6,3) network assembled by lanthanide and 2,2‐dihydroxylmalonate. X‐ray analysis re‐vealed that each lanthanide center is surrounded by three 2,2‐dihydroxylmalonate ligands with bis‐chelate coordination mode to give rise to a building unit of turbine blade structure. These buiding units alternatively connect adjacent units with same configuration and extend the linkage on ab plane to form the chiral two‐dimensional framework. The construction of the resultant chiral network demonstrates that 2,2‐dihydroxylmalonate is a perfect ligand to build some chiral metal‐organic framework with potential optical properties. More details are discussed in the article by Zhang et al. on page 228–232.
