In this HOT Article, the achiral mesoxalato ligand (H2mesox2-) is identified as a new enantiopurity enforcer in extended structures by yielding the homochiral metal-organic frameworks (MOFs) 2D-[Ln2(µ-H2mesox)3(H2O)6]. The chirality of the compounds can be observed in the features of the crystal structure and also in the dominating intensity of the hypersensitive transition within trivalent europium, which reacts strongly to the absence of a local inversion centre and proves the chiral environment of the rare-earth ions within the complexes.
