Chemical Characterization of a Volatile Dubnium Compound, DbOCl3
The 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 350â600â°C. Under the exactly same chemical conditions, comparative studies with the lighter homologues of Groupâ
5 in the Periodic Table clearly indicate the volatility sequence being NbOCl3 > TaOCl3 â„ 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
