Figure 1
View of the asymmetric unit of (I) (with formate ions completed by symmetry), showing 50% displacement ellipsoids (arbitrary spheres for the H atoms). Cs, H, Na and O atoms are green (large), green (small), blue and red, respectively. [Symmetry codes: x, − − y, z (for O2A and O4A); x, − y, z (for O3A and O5A)]. |
