| Popis: |
A hydrolyte of magnesium 7-methoxyl-4′-hydroxylisoflavone-3′-sulfonate ([Mg(H2O)6](C16H11O4SO3)2·10H2O) was synthesized and its crystal structure was determined by X-ray diffraction analyses. The crystal belongs to triclinic crystal system, space group P-1 with cell constants a = 0.7359(1) nm, b = 0.9935(1) nm, c = 1.6335(2) nm, α = 91.16(1)°, β = 92.07(1)°, γ = 106.53(1)°, V = 1.1436(2) nm5 and Z = 1. The results show that the title compound consists of [Mg(H2O)6]2+, C16H11O4SO3- and H2O. Mg(II) is located at the symmetry center of the title compound. [Mg(H2O)6]2+, C16H11SO3− and H2O form fourteen kinds of hydrogen bonds. The distance of 0.351 nm between parallel isoflavone rings shows a #-# stacking interaction. The hydrogen bonds and #-# stacking interaction lead to supramolecular formation with three-dimensional network structure. The title compound was also characterized by IR and 1H NMR spectra. |
