Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, SDS of cas: 33100-27-5.
Three Eu(II) complexes with crown ethers were obtained by electrochemical reduction. The complex with 12-crown-4 contains Eu bonded to four O crown atoms, three water molecules and a chloride anion, and shows luminescence at 429 nm at room temperature and at 410 nm at 77 K. The bis(15-crown-5)europium(II) cation has a sandwich structure with 10-coordinate metal ion. Its luminescence has the maximum at 433 nm at room temperature and at 417 nm at 77 K. The weakly luminescing (411.5 nm at 77 K) bisperchlorato(18-crown-6)europium(II) is also 10-coordinate; both perchlorate anions are bonded in a chelating bidentate fashion. The luminescence lifetimes and the excitation spectra are discussed.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 33100-27-5. In my other articles, you can also check out more blogs about 33100-27-5
