Infrared spectroscopic and gravimetric studies on the dicyclohexylaminecadmium(II) tetracyanopalladate(II) host-aromatic guest systems

Abstract

The host complex Cd(Cyclohexylamine)(2)Pd(CN)(4) has been prepared in powder form. The spectral data suggest that the structure of this complex is similar to those of the Hofmann-dma-type hosts. The sorption processes of the aromatic guests (benzene, toluene, o-, m-, p-xylene, naphthalene, 1,2-, 1,3-, 1,4-dichlorobenzene and 1,4-dibromobenzene) in this host have been examined at room temperature by gravimetric and spectroscopic measurements. The desorption of the benzene guest against time has been measured. The host structure changes on inclusion of the guests and recovers after liberations. The host complex has been suggested as sorbents for selective absorption.
