Figure 1
A PLATON (Spek, 2003) view of the polymeric unit of (I), shown with 50% probability displacement ellipsoids. Labels of asymmetric unit atoms, all Na atoms, and atoms O9C and O10C are shown. Atoms labelled with the suffixes A, B and C are at the symmetry positions (y, 1 − x, 1 −z), (1 − x, 1 − y, −z) and (1 − y, x, 1 − z). |
