The hydrogen bonding based on the MAM. (a) The bond paths of hydrogen bonding along the electron distribution of the chromophore. (b) Details of the bond paths around Oη. (c) Details of the bond paths around O2. The cyan surfaces represent the deformation electron density at contour levels of +0.01, +0.15 and +0.5 e Å−3, respectively. The bond paths for conventional hydrogen bonds are represented as green curves, while those for nonconventional bonds are represented as pink curves. The De values for hydrogen bonds (in kJ mol−1; listed in Supplementary Table S5) are shown in parentheses.
