Self-Assembly of 1,1′-Biphenyl-2,2′,6,6′-tetracarboxylic Acid: Formation of an Achiral Grid with Chiral Compartments

Abstract

-symmetric chiral hydrogen-bonded cyclotetramers (see the structure in the picture) are present in the self-assembled achiral title compound in the solid state. The unilayered network set up from the chiral "square" blocks is achiral as a consequence of the crystal symmetry.
