Ab initio crystal structure determination of β-sodium acetate from powder data

Published/Copyright: July 28, 2010

Abstract

The crystal structure of β-sodium acetate, NaC2H3O2, has been determined from X-ray powder diffraction data. Grid search and Rietveld refinement have been used to determine the structure. The crystal symmetry is orthorhombic (space group Pmn21, Z = 2) and the unit cell parameters are a = 3.4517(5) Å, b = 9.9123(11) Å and c = 5.1864(6) Å. Soft constraints have been applied to the molecule. The final RF value obtained was 7.5%.
