This paper describes the data on synthesis of bis(cyclopentadienyl)vanadium(III) of pentacarbonyl rhenium bistetrahydrofuranate complex with the reaction between dicyclopentadienylvanadium (III) chloride and rhenium sodiumpentacarbonyl in tetrahydrofurane (THF). Formed in this case the target product was separated from reaction mixture by extracting with hot hexane. Their reactionary ability in relation to protonic and aprotonic acids Lewis had been inverstigated. It is revealed, that at interaction of the above mentioned complexes with HCl there is a splitting Re-V bond with formation (C₅H₅)₂VCl and HRe(CO)₅; (C₅H₅)₂VCl and HRe(CO)₄PPh₃ respectively. At interaction with HgCl₂ also occurs having break V-Re bond and it turn out (C₅H₅)₂VCl and (OC)₅ReHgCl; (C₅H₅)₂VCl and PPh₃(OC)₄ReHgCl. The interection of these complexes with ligands of various dentate is investigated. A monodentate liqand-triphenil phosphine (PPh₃) substitutes one of carbonyl-groups in Re(CO)₅) - fragment. Bidentate liqand- acetylacetone (acac) easily push out from coordination sphere vanadium more donor liqand - cyclopentadienyl. The composition and structure of the complexes were characterized by the data of NMR, IR, EPR-spectroscopy and thermal analysis.
