Abstract and Comment. I do not believe that the purported intramolecular C--H...O interaction has any structural importance (the angle around H is much too small). Delete all references to this. The bifurcated R^1^~2~(6) motif involving O2, H3A and H7A is more interesting, but you do not mention this (you should do so). More information is needed about pi...pi interactions. Are they edge-face or face-face? If edge-face, then what is the C-H pointing at? Centre of the ring? C=C? Allyl fragment? Butadiene fragment? If face-face, then what is the slippage as well as the centroid-centroid distance? 3. Redraw Figure 2 using only those H atoms involved in C--H...O interactions. The picture will be much clearer and will show that a hydrogen-bonded ribbon is formed by the R^1^~2~(6) motif. |

If face-face, then what is the slippage as well as the centroid-centroid distance? the intramolecular C--H...O interaction has not importance. the intrermolecular C7--H7a...O2 interaction is very important. there is one pi...pi interaction, C1-C6 rings. 3. Redraw Figure 2 using only those H atoms involved in C--H...O interactions. The picture will be much clearer and will show that a hydrogen-bonded ribbon is formed by the R^1^~2~(6) motif. R^1^~2~(6) motif? i question it . |
