Abstract: No diffraction data of Sodium Hydroxyacetate(sodium glycolate) has been reported in X-ray powder diffraction files. It is shown that the result of index research of the X-ray powder diffraction pattern of sodium hydroxyacetate was refined carefully. The refined unit cell parameters for orthorhombic system of sodium hydroxyacetate are: a =1.0581(1) nm, b =0.6440(1) nm, c =0.5303(1) nm, V =0.3613(1) nm3 , Z =4 , Dx=1.802 g·cm-3 , Dm=1.786 g·cm-3 , F20 =38, F30=51(0.0088, 68), F59=48(0.0081, 153). Extinction conditions indicate that the space group is P21212(18).
