Abstract: | P,P′-(2,5-Dihydroxy-3,6-dimethyl-2,5-dioxo-2λ5,5λ5-1,4,2,5]dioxadiphosphinane-2,5-diyl)-bis-phosphonic Acid The tetrahydrate 1 of the title compound crystallizes in the monoclinic space group P21/c with a = 845.8, b = 1 098, c = 981.7 pm, β = 113.02° and Z = 2. The anions of the oxonium compound (H3O+ · H2O)2(C4H10O12P42?) are layered by hydrogen bridges. The 1H, 13C and 31P NMR spectra (4 and 5 spin systems) are discussed. |
