VIBRATIONAL SPECTROSCOPIC INVESTIGATION ON SOME HOFMANN-TdTYPE CLATHRATES: Ni(1,9-DIAMINONONANE)M(CN)4.2G (M = Cd OR Hg, G = 1,3-DICHLOROBENZENE)

Öz

New Hofmann-T_d-type clathrates in the general form of Ni(1,9-diaminononane)M(CN)₄.2G (M = Cd or Hg,                1,9-diaminononane = danon, G = 1,3-dichlorobenzene) have been prepared in powder form and their FT-IR and Raman spectra have been reported in the range of (4000–200) cm^-1 and (2850–1650) cm^-1, respectively. The spectral results suggest that these compounds are similar in structure to the Hofmann-T_d-type clathrates.
