Tribromohydroxyphosphonium Hexafluorometalate: Synthesis, Spectroscopic Characterization, and Crystal Structure of Br3POH+AsF6-
摘要:
The reaction of tribromophosphine oxide in the superacidic systems XF/MF5 (X = H, D; M = As, Sb) leads to tribromohydroxyphosphonium hexafluorometalates. The structure was successfully elucidated in the case of tribromohydroxyphosphonium hexafluoroarsenate. Br3POH+AsF6- crystallizes in the orthorhombic space group Pnma (No. 53 with a = 1292.5(l) pm, b = 871.6(l) pm, and c = 845.0(1) pm) with four formula units per cell. The Raman, IR, H-1 NMR, and P-31 NMR spectra of Br3POX+MF6- (X = H, D; M = As, Sb) are reported.
