First principles calculations on the hybrid perovskite CH3NH3PbI3 predict strong hydrogen-bonding which influences the structure and dynamics of the methylammonium cation and reveal its interaction with the tilting of the PbI6 octahedra. The calculated atomic coordinate... View more

    As a way of visualising the hydrogen-bonding in o-MAPbI3, we present in Fig. 4 the non-covalent interaction isosurfaces calculated using the Critic2 code26,27 for the ground-state and
