    Notes: Abstract Four new clathrates of the formula M(Im)2Ni(CN)4·2·Dioxane (where M = Co, Ni, Cu, Cd; Im = Imidazole) have been prepared in powder form and their FT-IR and laser-Raman spectra are reported for the first time. These clathrates are analogues to the previously reported classical Hofmann type clathrates except for the copper clathrate. The Cu clathrate has different spectral features in comparison with its analogues due to the Jahn-Teller effect.

    Topics: Chemistry and Pharmacology
    Notes: Abstract Three dimensional host lattices have been developed by forming bridges with bidentate pyrazine molecules between adjacent tetracyanonickelate polymeric layers of Ni(II) or Cd(II). The Fourier-transform IR and Raman spectra (4000-200 cm−1) of the compounds with the general formula M(pyz)Ni(CN)4, (where M = Ni or Cd) are reported. These host lattices can include benzene molecules but it is found that aniline molecules cannot be included in these structures. They, however, form complexes with the formula M(an)2Ni(CN)4, by replacing pyrazine ligands. A monodentate pyrazine complex of Cd(II) with the formula Cd(pyz)2Ni(CN)4 has also been prepared.

    Keywords: IR and Raman spectra ; 4,4′-bipyridyl ; tetracyanonickelate clathrates

    Topics: Chemistry and Pharmacology
    Notes: Abstract The infrared spectra of M(4,4′-bipyridyl)Ni(CN)4 complexes (M=Ni or Cd) and their dioxane, benzene, toluene, aniline andN,N-dimethylaniline clathrates are reported. Additional information regarding the structure of the host lattice is obtained from the Raman spectra of the M=Cd complex. It is shown that the structure of the host lattice consists of infinite polymeric layers of {M-Ni(CN)4}∞ analogous to those of Hofmann type clathrates that have tetragonal symmetry. Bidentate 4,4′-bipyridyl molecules form bridges between the metal atoms {M} in the adjacent {M-Ni(CN)4}∞ layers. It is found that the 4,4′-bipyridyl molecules are centrosymmetric in this structure.
