Co(Cyclohexylamine)(2)Ni(CN)(4) and Cd(Cyclohexylamine)(2)Ni(CN)(4) host compounds have been prepared in powder form. The spectral data suggest that these complexes are similar in structure to the Hofmann-dma-type hosts. The sorption processes of the aromatic guests (benzene, toluene, o-, m-, p-xylene, naphthalene, 1,2-, 1,3-dichlorobenzene and 1,4-dibromobenzene) in these hosts have been examined at room temperature by gravimetric and spectroscopic measurements. The desorption of the benzene guest against time has been measured. The host structures change on inclusion of the guests and recover after liberation. The host complexes have been suggested as sorbents for isomeric separations.
