Abstract

The sodium-magnesium hydrated double salt konyaite, Na(2)Mg(SO(4))(2)center dot 5H(2)O, has been studied by single-crystal X-ray diffraction and thermogravimetry on synthetic samples and by quantitative X-ray diffraction utilizing the Rietveld method on natural samples from the Mount Keith mine, Western Australia. Konyaite crystallizes in space group P2(1)/c, with the cell parameters: a = 5.7594(10), b = 23.914(4), c = 8.0250(13) angstrom, beta = 95.288(9)degrees, V = 1100.6(3) angstrom(3) and Z = 4. The crystal structure has been refined to R(1) = 3.41 for 2155 reflections [F(o)>4 sigma(F(o))] and 6.44 for all 3061 reflections, with all atoms located.
