    FT-IR spectroscopic investigation of some Hofmann type complexes: M(2-(1-Cyclohexenyl)ethylamine)2Ni(CN)4 (M = Ni, Co)
    (Elsevier Science Bv, 2008) Izgi, Tekin; Parlak, Cemal; Aytekin, Tuerkay; Senyel, Mustafa
    New Hofmann type complexes in the form of M(CyHEA)(2)Ni(CN)(4) (where CyHEA = 2-(1-cyclohexenyl)ethylamine; M = Ni or Co) have been prepared in powder form and their infrared spectra have been reported in the range of 4000-400 cm(-1). The thermal behaviour of these complexes has been investigated by differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA). The results suggest that these compounds are similar in structure to Hofmann type complexes and their structures consist of polymeric layers vertical bar M-Ni(CN)(4)vertical bar(infinity) with the CyHEA molecule bound to the metal atom (M).

    Vibrational spectroscopic investigations of some Hofmann-Td-type complexes: Ni(2-(1-cyclohexenyl)ethylamine)2M(CN)4 (M = Cd or Hg)
    (Pergamon-Elsevier Science Ltd, 2010) Izgi, Tekin; Parlak, Cemal; Senyel, Mustafa
    New Hofmann-T-d- type complexes in the form of Ni(CyHEA)(2)M(CN)(4) (where CyHEA = 2-(1-cyclohexenyl)ethylamine and M = Cd or Hg) have been prepared in powder form and their infrared (4000-100 cm(-1)) and Raman (2800-1650 cm(-1)) spectra have been reported. The thermal behaviour of these complexes has been investigated by differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA). The results suggest that these compounds are similar in structure to the Hofmann-T-d-type complexes. (C) 2009 Elsevier B.V. All rights reserved.

    Vibrational spectroscopic study on some Hofmann type clathrates: M(2-(1-cyclohexenyl)ethylamine)2Ni(CN)4•2benzene (M = Ni and Cd)
    (Pergamon-Elsevier Science Ltd, 2011) Izgi, Tekin; Parlak, Cemal; Senyel, Mustafa
    New Hofmann type benzene clathrates in the form of M(CyHEA)(2)Ni(CN)(4)center dot 2benzene (where CyHEA= 2-(1-cyclohexenyl)ethylamine and M=Ni or Cd) have been prepared in powder form and FT-IR and Raman spectra have been reported. The results suggest that title compounds are similar in structure to Hofmann type clathrates and their structures consist of polymeric layers of vertical bar M-Ni(CN)(4)vertical bar(infinity) with the CyHEA molecule bounded to the metal atoms (M).
