Vibrational spectroscopic and gravimetric study of some hofmann-CBA-type host and host-guest compounds

ABSTRACT PhD Thesis VIBRATIONAL SPECTROSCOPIC AND GRAVIMETRIC STUDY OF SOME HOFMANN-CBA-TYPE HOST AND HOST-GUEST COMPOUNDS M. TÜRKAY AYTEKİN AYDIN Anadolu University Graduate School of Sciences Physics Program Supervisor: Prof. Dr. Mustafa ŞENYEL 2005, 102 pages In this study, similar to Hofmann type M(C4H7NH2)2Ni(CN)4 (M=Ni or Co) host and M(C4H7NH2)2Ni(CN)4.nG (M=Ni or Co; GHbenzene, 1,2-, 1,3-, 1,4-dichlorobenzene, naphthalene; n=the number of guest) host-guest compounds were obtained chemically. The infrared spectra of these compounds were recorded with FT-IR spectrometer in the spectroscopic region of 4000cm"1-400cm"1 from these spectra the vibrational wave number of ligand molecule, Ni(CN)4" ion and guest molecules were determined. The absorption and the liberation processes of the guest molecules in the host compounds were examined at room temperature by gravimetric method. Otherwise, it was seen that the molecular structure was supported by making instrumental analysis of host and some host-guest compounds. By analysing the structures of host and host-guest compounds were found to be similar to those of Hofmann type compounds, ligand molecule cyclobutylamine were coordinated to M metal atom from cyclobutylamine's nitrogen atom, the guest molecules were imprisoned in the structural cavities between the sheets.
