The possibility of resorption of a guest molecule (G) or its substitution by other compounds is not known for M(NH3)2N(CN)4.2G (G = C6H6) or M(en)mM'(CN)4.nG clathrates, or even for the parent M(NH3)mM'(CN)4.nH2O, MM'(CN4).nH2O tetracyano complexes. These, however, are capable of sorption, and their lattice space can be reversibly or irreversibly filled with a suitable organic compound if the clathrates or tetracyano complexes in the hydrated form are allowed to be in contact with organic substances whose size and polarity fit the tetracyano complex lattice. The space within the lattice, however, develops as early as their formation from solution or suspension in the presence of the compound G (presence of water is actually sufficient).
