Crystalline Inclusion Compounds of 2,2′-Dihydroxy-1,1′-binaphthyl with Alkali Metal Hydroxides and Ammonia

Abstract
2,2′-Dihydroxy-1,1′-binaphthyl, C20H14O2 from crystalline inclusion compounds of stoichiometries 1\frac12C20H14O2·3MOH·8H2O (M = Li,Na,K), C20H14O2·CsOH·6H2O, and 2C20H14O2·2NH3·CH3OH. In the crystal structure of the NH3 complex, the three molecular components are interlinked by hydrogen bonds to form a column with a hydrophilic stem and a hydrophobic sheath.
