dcterms:description
Two types of vanadocene complexes with carboxylic acids have been synthesized from the aqueous solution, Cp2V(OOCR)2 (R=H, CH3 and CF3) and Cp2V(OOC-A-COO) (A= ů and CH2), and characterized by EPR, IR, and Raman spectroscopy and X-ray diffraction analysis. Monocarboxylic and dicarboxylic acids form bidentate and chelate complexes, respectively. Both bonding types were evidenced by X-ray diffraction analysis. Structures and EPR HFC tensors were also calculated at the DFT level. Correlation between the complex structure and HFC tensor was established. HFC tensors are characteristic for the type of bond of carboxylic acid on vanadocene fragment. It is shown that the structure of complexes can be determined by the combination of theoretical method with experimental EPR spectra. Byly syntetizovány dva typy vanadocenových komplexů s karboxylovými skupinami z vodného roztoku Cp2 V(OOCR)2 a Cp2 V(OOC-A-COO) a byly charakterizovány EPR, IR a Ramanovou spektroskopií a rtg analýzou. Monokarboxylové a dikarboxylové kyseliny tvoří monodentalové respichelátové komplexy. Oba typy byly prokázány rtg analýzou. Struktury a EPR HFC tenzory byly též vypočítány na DFT úrovni. Byla stanovena korelace mezi strukturou komplexu a HFC tenzorem. HFC tenzory jsou charakteristické pro typ vazby karboxylové kyseliny na vanadocenovém fragmentu. Je ukázáno, že strukturu komplexů lze určit kombinací teoretického výpočtu a experimentálních EPR spekter Two types of vanadocene complexes with carboxylic acids have been synthesized from the aqueous solution, Cp2V(OOCR)2 (R=H, CH3 and CF3) and Cp2V(OOC-A-COO) (A= ů and CH2), and characterized by EPR, IR, and Raman spectroscopy and X-ray diffraction analysis.
