Figure 1
The crystal structure of the three-dimensional perovskite cage compound (I) at room temperature. H atoms bonded to formate C atoms have been omitted for clarity. The non-H atoms of an asymmetric unit are labelled. Displacement ellipsoids were drawn at the 30% probability level. Dashed lines indicate hydrogen-bond interactions.
