САЖЕТАК / ABSTRACT:
Two slightly different manner of syntheses lead to the formation of four molecular complexes with two type of coordination arrangement; brown complexes VO(iPrO)(dBrQ)2 (1), VO(iPrO)(5I7BrQ)2 (2) and dark green VO(Cl)(dBrQ)2 (3), VO(iPrO)(5I7BrQ)2 (4). The presence of water and isopropanol in synthesis plays a crucial role in the formation of these two types of complexes. Otherwise also some dinuclear oxo-bridged complexes with four quinoline-8-ol derivatives coordinated to vanadium (V) were obtained in this reactions scheme. The mononuclear complexes were characterized by elemental analysis, infrared spectroscopy and X-ray structure analyses. The stability was tested by UV-VIS and NMR spectroscopy and showed some differences in accordance of solvent and also structure of complexes. The first results of biological activity will be reported, too.
