Interactions in molecular crystals, 147 - Isostructural host/guest-inclusion compounds of N,N '-ditosyl-p-phenylenediamine with acetone, cyclopentanone, cyclopent-2-ene-1-one, 1,3-dioxolane, tetrahydrofurane, and 2,5-dihydrofurane

Six isostructural inclusion compounds of various ketone and ether guest mol ecules into the hydrogen-bonded host-matrix of N,N'-ditosyl-p-phenylenediam ine are presented. Crystal growth, structure determinations as well as the arrangement within the clathrates formed is reported and discussed in detai l. Packing coefficients and especially the volume ratios between the guest- containig channels and the unit cells allow to estimate the size limit of g uest molecules, which can cocrystallize. Additional crystal growth experime nts yield information concerning other types of guest molecules, inclusion from solvent mixtures and guest removal as well as guest exchange processes observed for the N,N'-ditosyl-p-phenylenediamine host matrix.
