Syntheses and crystal structures are reported for a new class of hosts, their complexes, and their precursors. The cryptahemispherands are composed of molecular modules that are half spherand and half cryptand. They were synthesized by the reactions of diacid chloride and cyclic diamines to produce diamides, reduction of which gave the desired hosts. Cryptahemispherands form a variety of complexes with the alkali metal cations. Crystal structures were determined for the isomeric diamides for the hydroborane complex, and for alkali cation complexes.
