|a Methylammonium lead iodide (CH3 NH3 PbI3 ) perovskite compound has produced a remarkable breakthrough in the photovoltaic history of solar cell technology because of its outstanding device-based performance as a light-harvesting semiconductor. Whereas the experimental and theoretical studies of this system in the solid state have been numerously reported in the last 4 years, its fundamental cluster physics is yet to be exploited. To this end, this study has performed theoretical investigations using DFT-M06-2X/ADZP to examine the principal geometrical, electronic, topological, and orbital properties of the CH3 NH3 PbI3 molecular building block. The intermolecular hydrogen bonded interactions examined for the most important conformers of the system are found to be unusually strong, with binding energies lying between -93.53 and -125.11 kcal mol-1 (beyond the covalent limit, -40 kcal mol-1 ), enabling us to classify the underlying interactions as ultra-strong type since their characteristic properties are unidentical with those have already been proposed as very strong, strong, moderate, weak, and van der Waals. Based on this, together with the unusually high charge transfers, strong hyperconjugative interactions, sophisticated topologies of the charge density, and short intermolecular distances of separation, we have characterized the conformers of CH3 NH3 PbI3 as Mulliken inner complexes. The consequences of these, as well as of the ultra-strong interactions, in designing novel functional nanomaterials are outlined. © 2017 Wiley Periodicals, Inc
