Trapped water : Six molecules of water are trapped in the crystal lattice of an organic supramolecular complex with bimesityl‐3,3′‐dicarboxylic acid in the form of a planar cyclic “ring”, which is the basic structural motif of Ice II. The water molecules of the hexamer (see picture) are associated in the crystal lattice by eighteen OH⋅⋅⋅O hydrogen bonds.
