The point that is crucial here is that ionic compounds are held together in a crystal lattice structure. What you have misunderstood is that there are no intermolecular forces between these ions, as number one the forces are not between molecules but ions, and number two if you break the bonds between a $\ce{Na+}$ and a $\ce{Cl-}$ ions, you …This can be attributed to the huge difference in solubility of CsBr and PbBr 2 in DMSO, which leads to the precipitation of either CsBr- or PbBr 2-rich compounds alongside the desired CsPbBr 3 perovskite 16. Typically, only upon an increase of the PbBr 2 fraction to form CsBr:PbBr 2 (1:2) solution, CsPbBr 3 crystals can dominate the product [email protected].
