1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Recommanded Product: 66943-05-3

Crown-templated assembling of the inorganic binuclear fluoro-containing anions in the system ZrO2/HfO2 (Nb2O5/Ta2O5)-HF-H2O-azacrown ether was written by Fonari, Marina S.;Kravtsov, Victor Ch.;Simonov, Yurii A.;Basok, Stepan S.;Ganin, Eduard V.;Gelmboldt, Vladimir O.;Suwinska, Kinga;Lipkowski, Janusz;Alekseeva, Olga A.;Furmanova, Nina G.. And the article was included in Polyhedron in 2008.Recommanded Product: 66943-05-3 This article mentions the following:

The interaction of ZrO2/HfO2 or Nb2O5/Ta2O5 with an aqueous solution of hydrofluoric acid in the presence of aza-crown ether resulted in novel organically templated metal oxyfluorides [(HA15C5)2][Ta2F10O] (1), [(HA18C6·H2O)(A18C6·H2O)][(H2O)Nb2F9O]·H2O (2), [(HA18C6·H2O)(M2F10·2H2O)·(H3O)·H2O] (3, 4) and [(H2DA18C6)(M2F10·2H2O)·2H2O] (5, 6) (M = Zr, Hf, A15C5 = aza-15-crown-5, A18C6 = aza-18-crown-6, DA18C6 = diaza-18-crown-6). Complexes 1–6 were identified by single crystal x-ray diffraction. In 1, the neg. charge of the [(TaF5)2O]2- centrosym. dianion is balanced by two azonia-15C5 cations, while in 2 the charge of asym. [(H2O)NbF4ONbF5]– monoanion is compensated by azonia-18C6 cation. The crystal of 2 revealed an extensive hydrogen bonding between the anions, protonated and neutral macrocycles and water mols. that combine the components into 2-dimensional sheets. Complexes 3–4 and 5–6 are isostructural in pairs; in all of them the rigid 2-dimensional inorganic motif is formed through the association of the [(M2F10·2H2O)]2- anions by OH···F hydrogen bonds. The similar 3-dimensional supramol. architecture in 3–6 represents an alternation of the neg.-charged inorganic sheets and the columns of (HA18C6)+ or (DA18C6)2+ organic cations glued by oxonium cations or water mols. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Recommanded Product: 66943-05-3).
