Synthesis and study of complex compounds of Rhenium with o-fenantrolin and benzimidazole
Abstract
Processes of a complex formation of rhenium (V) compounds with o-fenantroline and benzimidazolwere investigated. The composition and a structure of the received compounds were proved by various physical and chemical methods. By results of the carried-out researches itwas established that at synthesis of fenantroline complexes there is a regrouping caused by a dehydrohalogenation and transition of outer spherical ligand in the internal sphere of a complex. The composition of benzimidazole complexes depends on the concentration of HX (X = Cl, Br) in the medium. At high concentrations thre are complexes of onium-type, at low concentrations of complexes - with monodentate ligands coordinated via the nitrogen atom is unsubstituted imidazole ring.
