Hofmann-dabn-type inclusion compounds

The Hofmann-dabn-type inclusion compounds were prepared by the method described in the previous communication [6] in Table I the results of elemental analyses and the basal spacings estimated from the powder X-ray diffraction patterns are listed. They are not stable under ambient condition but the rates of decomposition are slow enough to be subjected to the elemental analyses if the specimens are kept in tightly capped vials some of them, marked with an asterisk in the Table I, are rather unstabe, however.

One of the problems to be solved for the formation trend of Hofmann-(long-carbon-chain a,oo-diaminoalkane)-type series of inclusion compounds is to interpret the reason why Hofmann-dahxn-type host cannot accommodate xylidines as guest, which Hofmann-dabn-type host can do even with the shorter carbon chain in the full length than dahxn. In order to solve the problem we need more information about the crystal structures of the series. The structure analyses of Hofmann-dahxn-type m-and p-toluidine inclusion compounds are in progress.
