Abstract
Effective methods for the synthesis of a number of complex compounds of rhenium (V) with 1, 10 - phenanthroline have been developed. The composition and structure of the obtained compounds were proved by physico-chemical methods, and their properties were studied by methods of elemental analysis, IR and electron (ESP) spectroscopy and thermogravimetry. Compounds of the composition PhenH2[ReOCl5](I) and PhenH2[ReOBr5](II) were obtained. The [ReOХ3Phen]- (III and IV) (x=Cl, Br) compounds were synthesized by thermal decomposition I and II. It is shown that thermal decompositions I and II proceed with the release of the corresponding hydrogen halide and the rearrangement of the phenanthroline molecule. The transition of phenanthroline from the external sphere (I and II) to the sphere of the ligand environment of rhenium (V) (compounds III and IV) was confirmed by the results of spectrophotometric measurements (IRS, ESP).
Keywords: complexes of rhenium, nitrogen containing organic liqands, o-phenantroline.
