Covalently linked dipyrrin (dipyrromethene) dimers have afforded nanoscale [2+2]-type neutral coordinationmacrocycles with a diagonal of about 1.6 nm. Two moieties of the achiral dipyrrin-Zn(II) complex yield the chiral coordinationmacrocycles as minor species, as well as major meso stereoisomers by the covalent linkages. Tetrahedral Zn(II) coordination by using acyclic ligands enables the dipyrrin-metal
