A class of novel inclusion compounds based on the hydrogen-bonded host lattice of N,N′- ditosyl-p-phenylenediamine is the starting point for the investigation of derivatives such as N,N′- di(4-ethyl-benzosulfuryl)-p-phenylenediamine. Structures of both the guest-free compound and of its clathrates with acetone as well as cyclopentanone suggest a considerable enthalpy of formation contribution from the conformational change of the sulfonamide backbone on adaption of the guest molecules. The host channels of the N,N′-ditosyl-p-phenylenediamine inclusion compounds are compared to those of the ethyl derivative elongated by two H2C substituent units, and the crystal packing in its cyclopentanone clathrate with an unexpected type of bulged channels is emphasized.
