HIGH-SYMMETRY INCLUSION-COMPOUNDS WITH MIXED GUESTS

2,2'-Bis(hydroxydiphenylmethyl)-1,1'-biphenyl, H, forms two structural ly similar inclusion compounds, H . H2O . 1/6benzene (compound 1) and H . 2 1/6H(2)O (compound 2). In both crystal structures, six host mole cules form a cyclomer linked via hydrogen bonding to bridging water mo lecules. In the case of compound 1 the resulting cavity encapsulates a benzene molecule, whereas compound 2 includes a total of 2 1/6 molecu les of water per host to form an inclusion compound with an intricate H-bonding pattern.
