Popis: The time-dependent changes which are observed in the infrared and Raman spectra of samples of the two Hofmann aniline clathrates M(NH 3 ) 2 Ni(CN) 4 .an 2 {M = Cd(II), Ni(II), an = C 6 H 5 NH 2 } indicate the occurrence of a solid state ligand replacement reaction in which the aniline guest molecule replaces the coordinated ammonia to give Man 2 Ni(CN) 4 as the final product. The rate of replacement is greater for the cadmium than for the nickel clathrate, and for both clathrates evacuation of the sample greatly increases the rate of replacement. The Man 2 Ni(CN) 4 complexes can themselves act as host lattices forming clathrates containing guest molecules such as aniline.
