1,1'-Bis(hydroxydiphenylmethyl)- 9a, rac-1,1'-bis(1-hydroxy-1-phenylet
hyl)- 9b, rac-1,1'-bis(o-chloro-phenylphenylhydroxymethyl)- 9c and 1,1
'-bis(hydroxy-1-naphthylphenylmethyl)-ferrocene 9d were prepared as ho
st compounds, X-Ray crystal structures of 1:1 inclusion complexes of 9
a with MeOH and of 9b with dimethylformamide, and 9c itself were analy
