Chemical Characterization of a Volatile Dubnium Compound, DbOCl3

Angew Chem Int Ed Engl. 2021 May 12. doi: 10.1002/anie.202102808. Online ahead of print.ABSTRACTThe formation and the chemical characterization of single atoms of dubnium (Db, element 105), in the form of its volatile oxychloride, was investigated using the on-line gas phase chromatography technique, in the temperature range 350-600 °C. Under the exactly same chemical conditions, comparative studies with the lighter homologs of group-5 in the Periodic Table clearly indicate the volatility sequence being NbOCl3 > TaOCl3 ≥ DbOCl3. From the obtained experimental results, thermochemical data for DbOCl3 were derived. The present study delivers reliable experimental information for theoretical calculations on chemical properties of transactinides.PMID:33978998 | DOI:10.1002/anie.202102808
