Inclusion Properties of the New Host Compound 1,2,4,5-Tetra(morpholinocarbonyl)benzene and X-Ray Crystal Structure of Its 1:4 Complex with Water

Article abstract of DOI:10.1246/cl.1987.1025

The title host compound has been prepared and found to form inclusion complexes with water and a variety of alcohols.In its 1:4 crystalline complex with water, the host molecule occupies a centrosymmetric site, each non-adjacent pair of carbonyl oxygen atoms being bridged by two end-to-end hydrogen-bonded water molecules.The water molecules are further interconnected by hydrogen bonds to form two-fold screw spirals parallel to the b axis, giving rise to a layer structure.
