The common structural motifs in the title structures: (a) Na+(C3H5O2)−, (b) K+(C3H5O2)−, (c) Rb+(C3H5O2)- and (d) Cs+(C3H5O2)−. Displacement ellipsoids are shown at the 30% probability level. The cations, O, C and H atoms are shown as green, red, grey ellipsoids and as tiny light-grey spheres, respectively. |
