    • 3, the largest peak is 0.65. Therefore, compound 2a is considered to contain no solvent in the lattice. The asymmetric unit of 3 contains both solvent water molecules and EtOH molecules. The solvent EtOH molecules are disordered by translation over three sites, with site occupancy factors of 0.5, 0.25, and 0.25, respectively. CCDC 682963 (2a), 682964 (2b), and 682965 (3) contain the supplementary crystallographic data for this paper.

    • [14b] invoked this set of concepts in the description of chiral coordination polymers, because in the usual nomenclature, the term heterochiral does not distinguish between the R,S,R,S and R,R,S,S sequences. Herein, we feel comfortable following this nomenclature in describing supramolecular chirality, because of the similar dilemma encountered and the novelty of the structure of 3.
