...Hongwei Ma; David L. Bish; Hsiu-Wen Wang; Steve J. Chipera Abstract The crystal structure of sanderite, MgSO 4 ·2H 2 O, was determined from laboratory X-ray powder diffraction data measured from 2–140 °2𝛉 using Cu K α radiation. Sanderite is orthorhombic, space group P 2 1 2 1 2 1 , with unit-cell...
