Acta E 编辑的2个问题，诚求解答（重金酬谢）
|
|
发个单晶到Acta E, 遇到编辑有2个问题，超出自己范围，无法解答。恳请板块里的牛人帮忙。 问题如下： 1. 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. 请有能力解决这2个问题的高手跟帖确认，我再把数据给你。先谢谢了 |

1. 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.

The picture will be much clearer and will show that a hydrogen-bonded ribbon is formed by the R^1^~2~(6) motif. 这个还是比较好弄。 编辑提醒你怎么去做了，首先在摘要部分，你自己提到的C-H..O short contacts 可能编辑不是很认可。反倒他觉得另外一组典型氢键更加有意思一点，你提到的pi-pi堆积给出更多的信息，比如距离，角度等。而且指出是哪种Pi-pi？ 第二个就是重新画图。 |
