Es wird die Darstellung von reinem AsCl4F berichtet und sein Ramanspektrum angegeben. Dieses Chlor‐fluorarsoran ist bedeutend instabiler als AsCl2F3 und AsClF4.
At last, structural characterization of the P(OH)4+ ion (1; see picture) has been achieved through the transformation of H3PO4 with HF/MF5 (M=As, Sb). The phosphorus acids H3POn (n=2–4) react differently in the superacidic systems HF/MF5 (M=As, Sb): H3PO2 and H3PO3F form fluorophosphanes and hydronium salts, while H3PO4 gives thermolabile salts. The antimony compound P(OH)4+SbF6− has been crystallized and its crystal structure determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
