Polarized FTIR spectra investigation of the metallo-organic copper (Ⅱ) and nickel (Ⅱ) compounds

摘要

Was synthesized two copper (Ⅱ) complexes and one nickel complex of N-benzylidene-aniline derivatives and their ligands. We have performed polarized FTIR spectroscopy and X-ray diffraction measurements in wide temperature range ( 0- 220°C ) in order to establish correlation's among molecular, crystal and mesophase structures. We provided comparison of the FTIR and X-ray diffractometry results between well known metallo - organic copper (Ⅱ) complexes, which crystallizes in the monoclinic space group C2/c, with similar nickel complex. Investigated ligands and their metallo - mesogens are displaying the same sequence of the liquid crystalline phases - only with higher melting temperature for metallo - complexes
