    Adsorption of 2,2′-bipyridyl onto sepiolite, attapulgite and smectite group clay minerals from anatolia: The FT-IR and FT-Raman spectra of surface and intercalated species (1994)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 18 (1994), S. 123-135 
    Details
    ISSN: 1573-1111
    Keywords: FT-IR spectroscopy ; FT-Raman spectroscopy ; clays ; sepiolite ; attapulgite ; hectorite ; saponite ; bentonite ; adsorption ; 2,2′-bipyridyl

    Topics: Chemistry and Pharmacology
    Notes: Abstract The adsorption of 2,2′-bipyridyl by natural sepiolite, attapulgite, hectorite, saponite and natural and ion exchanged (Mn, Fe, Co, Ni, Cu, Zn or Sn) bentonites has been investigated by FT-IR and FT-Raman spectroscopy. Spectroscopic results indicate that most of the adsorbed molecules are coordinated to either exchangeable cations (in the case of smectite group clays) or Lewis acidic centres (in the case of sepiolite and attapulgite) as bidentate ligands. The formation of monoanionic surface species has also been detected, to a relatively small extent. No physisorbed surface species has been observed. XRD patterns and UV-visible spectra of the samples are also recorded for additional information.

    Clathrate and inclusion compounds. Part 11 [1]. A pre-resonance Raman study of the β-quinol/SO2 clathrate (1991)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 11 (1991), S. 389-396 
    Details
    ISSN: 1573-1111
    Keywords: Clathrate ; quinol/SO2 clathrate ; Raman spectroscopy ; pre-resonance Raman effect
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A pre-resonance Raman study of the yellow β-quinol/SO2 clathrate has been carried out using 609.8, 586.8, 514.5, 488.0 and 457.9 run excitation. Pre-resonance enhancement is observed for the guest vl (Al) band at 1147 cm−1 and the host band at 1257 cm−1. These observations are consistent with a charge transfer interaction arising from the LUMO of S02 (S 3pz) and the HOMO of quinol, which consists mainly of the ring π electrons.

    Clathrate and Inclusion Compounds. Part 12. Vibrational and NMR Spectroscopic Studies of Carboxylic Acid Guests in Dianin's Compound (1997)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 27 (1997), S. 179-190 
    Details
    ISSN: 1573-1111
    Keywords: IR spectroscopy ; Raman spectroscopy ; 13C-MAS NMR spectroscopy ; Dianin's compound ; clathrates ; carboxylic acids ; alcohols
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Infrared, Raman and solid state 13C-NMR spectra have been recorded for a range of clathrates of Dianin's compound containing straight chain aliphatic carboxylic acids (formic - octanoic) as guests. The IR, Raman and NMR spectra can be satisfactorily interpreted in terms of dimer (formic and acetic) and monomer (propionic - octanoic) occupation of the cavities. The clathrates containing straight chain alcohol guests (methanol - octanol) have also been prepared to aid in the interpretation of the NMR data.

    Vibrational Spectroscopic Investigations of M(Imidazole)2Ni(CN)4·2 Dioxane Clathrates (1999)

    ISSN: 1573-1111
    Keywords: Hofmann-type clathrate ; metal-imidazole complexes ; dioxane inclusion compounds ; IR and Raman spectra

    Topics: Chemistry and Pharmacology
    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.

    Clathrate and inclusion compounds. Part 8 [1]. An investigation of the usefulness of the spectral substraction technique in analysing the infrared spectra of clathrates (1985)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 3 (1985), S. 269-279

    ISSN: 1573-1111
    Keywords: Quinol clathrates ; Dianin's compound clathrates ; infrared spectra ; spectral subtraction technique ; difference spectra
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract An investigation has been carried out into the usefulness of the spectral subtraction technique in analyzing the infrared spectra of the clathrates of quinol and of Dianin's compound. Due to the flexibility of the quinol host lattice, it is not advisable to use guest-free β-quinol as the reference if the host lattice in the clathrate is considerably distorted, as it is in the CH3CN clathrate. In this case it is advisable to use another clathrate as the reference provided that the spectrum of the new reference does not contain guest bands in the region of interest. The Dianin's compound host lattice is less flexible than that of quinol, and guest-free Dianin's compound can be used as the reference irrespective of the size of the guest molecule. With both clathrates the spectral subtraction technique has revealed guest molecule bands which were previously obscured by host lattice bands.

    Vibrational spectroscopic studies of three dimensional host lattices formed by pyrazine bridges between tetracyanonickelate layers (1990)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 9 (1990), S. 349-354 
    Details
    ISSN: 1573-1111
    Keywords: Tetracyanonickelate compounds ; benzene clathrate ; pyrazine complexes ; IR and Raman spectra
    Source: Springer Online Journal Archives 1860-2000
    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 spectroscopy ; Raman spectroscopy ; 13C MAS NMR spectroscopy ; clathrates ; inclusion compounds ; carboxylic acids ; urea ; thiourea
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Infrared, Raman and solid state13C NMR spectra have been recorded for arange of inclusion compounds of urea containingstraight chain aliphatic carboxylic acids(butyric – decanoic) as guests. Inclusioncompounds are not formed with formic, acetic andpropionic acids. Thiourea does not forminclusion compounds with any of the C1 to C10acids. The vibrational and NMR data support theconclusion that the acids are present ashydrogen bonded dimers in the channels of thehost. The alkyl chain 13C chemical shiftvalues are very different from those of acidguests in the cavities formed in Dianin'scompound. These suggest that the alkyl chainsare present in the all-trans conformation,although weak bands observed in the spectrum ofthe decanoic acid inclusion compound lend somesupport to suggestions based on MM calculationsthat other conformations might be present.

    Vibrational spectroscopic studies of 4,4′-bipyridyl metal(II) tetracyanonickelate complexes and their clathrates (1987)

    Keywords: IR and Raman spectra ; 4,4′-bipyridyl ; tetracyanonickelate clathrates
    Source: Springer Online Journal Archives 1860-2000
    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.
